1 cylinder not firing

[thakid]

Ok my baby been acting up for some reason. Not sure why. I had it on a computer and was told one of the cylinders is not firing right. Car starts. Runs. Drives. But sometimes it likes to rock, hard to explain. It jumps my rpms from like 3 to 4 thousand. And when i am coming to a stop or down shifting to second but have not released the clutch it dies. I drop the clutch it fires back up. I was told it could be bad gas. So i dropped out the gas tank and drained it. I wanted to replace fuel filter but not sure where its at. Its an 03 ep3 si. Any help will be much appreciated. I only use 91 octane. I do not drive it. It has been sitting for the past couple days. Please help.

dizzzzzzzzzy man.
Or check your wires if its not firing

[24/7VTEC!!!!]

rotor,wire,injector?

rotor,wire,injector?

umm correct me if im wrong....but don't ep3's have k series? and don't k series use coil packs?? :roll: u guys :(

[FranktheTank]

hahaha I forgot what section we were in here when i post.

[24/7VTEC!!!!]

umm correct me if im wrong....but don't ep3's have k series? and don't k series use coil packs?? :roll: u guys :(

Never seen a k series in my life sorry....:ballin:

[IntegraDA]

lol its ok....google is you're friend ;)

[thakid]

im new to the k series. and dont know my way around this bad boy yet. but yes i know it doesnt have wires. i just replaced my plugs. my dizzy you say???? what could it be with the dizzy?

[IntegraDA]

there is no distributor...only crank and cam angle sensors. its most likely nothing with those...have you narrowed it down to which cylinder it is? ie: pull coil pack plugs until the engine mis firing doesnt change? pull out your plugs or use old plugs and pull out all the coil packs and see if they are getting spark to all 4. you will need some help with this one. do that first to narrow things down.

[thakid]

alright cool cool. when i find out what cylinder it is. what next?

[jakellama123]

just change your plugs and wires if they are sorta old
not bad to do either way

[thakid]

i already changed my plugs and the k series dont have wires.

[IntegraDA]

just change your plugs and wires if they are sorta old
not bad to do either way


seriously...if you would read, you would know both of those answers already ;)


and if one of the cylinders is not getting spark, lets say, try swapping coil packs with a known good one that you see sparking. If it still doesnt work, get a volt meter and check to see if the plug on the harness to the coil pack is getting power. If not, we can get into that...but for now, do the things i mentioned and we'll go from there :thumbup:

[thakid]

haha seriously. there are only like 8 replies in this thread. im not sure on what i should do to check which cylinder. im not engine smart. i learn as i go type.

[IntegraDA]

hold on...ill post up some detailed pics and I will show you what to do based on the pics you will see ;) gimme a few to 'paint' some pics

edit: here is a pic I made up real quick. pretty self explanatory at this point. ;)

smartass :( lol
sorry i dont know alot about k's
im focused on feeding my mind about boost right now lol

[IntegraDA]

lol as the other two people who posted this morning who thought they knew :) im not bashing just trying to keep threads clean. Now, go play with your b00st :grin:

[jakellama123]

i will!
its a work in progress

[IntegraDA]

coo coo...its a dsm...the work never ceases ;) but fun when done right dont get me wrong. now GTFO!









j/kj/k :snookems:

[thakid]

yo bro. thanks for the help. but i cant read whats written in the picture?

[IntegraDA]

make it bigger ;) are you on a phone?

[thakid]

nah on piece of dump i call my computer.

[jakellama123]

remove plug cover
pull plug off coilpack (keep engine running)
if engine sounds worse then its fine but if it doesnt change then it is in fact mis firing

[thakid]

okok i got it. had to click the image. sweeeeet. ill try this tonight. can i text you later dude for help?

[IntegraDA]

i go to bed early as f@ck cause i work early...send a pm...i get emails on my phone. If i'm up ill reply...if not, ill get back to you tomorrow AM :)

[thakid]

i had checked the coils. i unplugged each one at a time. and they all made my car bog down sorta and sound funny. Any other ideas? please and thank you.

[taggart_lumpy]

possibly dirty or clogged injector

are you throwing a cel?
if so what is the code

[thakid]

im not sure what the codes are. got a code chart? thanks

[taggart_lumpy]

take it to checker or autozone and have them write it down for you

[thakid]

the checker near me is full of dummies. they can hook it up to a computer or what?

[adam]

the checker near me is full of dummies. they can hook it up to a computer or what?

I'm pretty sure they should be able to, yeah. Lol And it should be okay even if they ARE dummies.. they just gotta hook it up and read off the screen.

[thakid]

i hope they can atleast pull of that simple task. ill ask them to let me do it. haha. could this be clogged injectors?

...

[Ls91ef]

go to checkers an get the codes pulled.....there is a sticky over on ephatch about what each code means you could check out

[thakid]

i cant check the forums. can you copy and paste them? thanks

[thakid]

okok i got the obd2 tool. ran it. heres my findings. i dont know how to fix. haha. so let me know
02 Circuit No activity Bank 1, Sensor 1 P0134
Cylinder 1,2,3,4 Misfire P0301 P0302 P0303 P0304
Random Misfire P0300

Iso 9141
I believe my EPS light comes on. Not sure what that is.

The check engine light is not always on. I had to rev up the car high and low a couple times for the check engine light to come on. Than it gave the codes. It has a really really nasty rich smell coming from the exhaust. Little white smoke.

Hope this helps you guys help me.

[thakid]

I erased it but.... when i turn car off and back on and re do the process. All the codes come back.

[EFin4Dr]

check your eld fuse under the dashboard if your eps light is on. could be that.

do all the codes come back on? if so which ones? integraDA seems to be one of the only ones that knows what they are doing so i would pretty much listen to him lol

is this the ep3 that used to be turboed? could be an aftermarket ecu or some tuning controller attached that is fucking the tune up.

check your sensors, and i wouldn't run it like that :( .

[thakid]

which sensors? names so i can look them up. thanks

[thakid]

Anyone. Help. Thanks

[24/7VTEC!!!!]

if you cant find the problem just take it to a mechanic already lol
GL

[thakid]

i wish i could. so unless they are willing to do it for less than a bill. haha. i cant.

[Ls91ef]

P0134 (41) Air Fuel Ratio(AF) Sensor(Sensor1) No Activity Detected

[IntegraDA]

just got back from ridin up north lol...sorry...so you rev it and white smoke comes out? yikes...do a compression test. white smoke USUALLY means you are burning coolant. If you have a blown HG/cracked head (worst case scenario), that would definitely cause a multiple/random mis-fire....but no usually on all four cylinders. This is a wierd synopsis of problems. Do a compression test and go from there.

[Ls91ef]

when i had my blown head gasket i was misfiring in #2.along with that white smoke..no fun at all

[IntegraDA]

yeah...its def a bummer :( It sounds like a blown hg at this point but I have to say...the fact that ALL four cylinders are mis-firing makes me rethink my diagnosis. It sounds strange...but to be safe and rule it in/out...we need to get a compression test done on this motor as soon as possible.

[Ls91ef]

time for a k24a2 i would say

[IntegraDA]

lol fun stuff ;)

[thakid]

damnnnnnn. i hope its not that. i gotta gather up some cash. nooooo

[poormansr]

Your coil pack went out. Im 100 % positive

[thakid]

you think? where can i get one? i am praying

[IntegraDA]

He already did the 'pull the wire to the coil pack while the engine is running' test...and all 4 packs changed the tone of the engine and running state...

you need to do a compression test and get that out of the way. it will take like 5 mins to do it. write down the numbers and let us know.

[EFin4Dr]

x2 on compression test. could have a warped head or block aswell.

[thakid]

fudge me running. im gonna pick up a compression tester tonight.

[RHD EF9]

Did p0135 store with p0134? if not try this. check the first 02 sensor on the cat, make sure its not loose, if it is unplug it, remove it, then reinstall it. if its not loose clear the dtc. turn the car on hold the rpms at 3k while its in neutral until the fans come on. if it comes back on replaced the a/f sensor #1. DO IT

[RHD EF9]

if you didnt get p0135 or p1166 that should be it

[thakid]

nah i posted all my codes i got. Im gonna check it right. costume party tonight too. dope.
i have not grab the compression tester. but will first thing in the morning

[RHD EF9]

Okay. Just tryin to help. Its not like I work for Dobbs Honda or anything... wait I do work there. Oh well

[mxtr]

this fucken guy ^ i work there to i would listen to him lol

[Ls91ef]

Okay. Just tryin to help. Its not like I work for Dobbs Honda or anything... wait I do work there. Oh well

:lmao:

hahahaha dooood. you a funny guy.

lol textbook response. Props on actually be intelligent lol

[thakid]

I just checked the sensor. Its the one in the middle of the cat correct? Its not loose. Should i unplug it anyways and reinstall it?

[thakid]

Alright i got the numbers from my compression test. Starting from left to right.
1)100 2)100 3)120 4)120

[thakid]

check your eld fuse under the dashboard if your eps light is on. could be that.

I looked under the dash. There is no eps fuse. The eps fuse is under the hood. But looks good. Not blown. So what could this be?

[RHD EF9]

Dooooode, look I don't do this for anyone, but if you come by my work at night I can check it out. Since you can't follow orders. Do you have a girlfriend cuz she'd whoop that ass for not listening

[thakid]

haha what you mean im not listening? im tryn haha. When and Where homie. I dont got cash. el brokeo. haha

[IntegraDA]

Alright i got the numbers from my compression test. Starting from left to right.
1)100 2)100 3)120 4)120


WHAT!???! dude thats horrible....did you crank the engine for 5 seconds or so on each cylinder while holding the throttle wide open?? the holding the throttle open wont make THAT drastic of a difference...but damn...that motor should not be running with those compression results! I would do it again...just to be sure.

[thakid]

i am not to sure on how to do a compression test so my drunk ass step dad was helping. I did not hold for five seconds or throw down pedal to the metal. What should my results be?

[IntegraDA]

upwards of the 200's... even for a mildly abused engine with high mileage should still read in the 190's 180's....i would re-do it. like I said before...that engine should not be running if the compression was that out of spec. just do it the same as you did the first time...except unplug all your injectors or pull the ecu fuse, and crank the motor for 5 seconds or so with the throttle wide open. do that and then post up your results...if they are still this low...start crying.

[84b18]

pull off the radiator cap and start it up if it shoots coolant out you have a blown head gasket. easy cheap test. let us know

[thakid]

Alright new results.
1) 175 1 75 175
2) 162 165 163
3) 158 169 169
4) 170 175 175


What you think?

[IntegraDA]

thats better than before....but something is still hurting internally i think. try doing a valve adjust to see if that helps any. what does the oil look like? what does the coolant look like? does it over heat? what do the spark plugs look like...in particular cylinders 2 and 3.

[thakid]

How do i do a valve adjustment? Oil and coolant look good. Doesnt over heat. Spark plugs were black from it being so damn rich but now the car is running great, doesnt feel full potential. But does drive without any check engine light. Im still not driving though. The spark plugs are brownish at the tips. They look good.

[IntegraDA]

hmm ok...well google k20 valve adjust and there will be plenty of writeups on how to do it. its too hard for me to explain if you havent done it before lol. Ill leave that to google.

[PhoenixB16]

If you havent done one before DO NOT do it without someone that knows how watching over your shoulder. You car FUCK something up with the wrong lash........And have you tried any of tghe shit that the tech's that posted here told you? Because they ARE tech for a reason..................

[thakid]

ive done everything they told me too. and that guy told me to bring my car by the shop and dint get back to me. whack.

[IntegraDA]

shit...so it does run ok now? it just lacks power? do you still have a CEL? Im confused about your last post...

[RHD EF9]

Sorry man Im trying to get a day I can get you in. Im not suppose to do side work there. So I gotta find a time Im available and my boss isn't there. So your compression test is tellin me its not a coil pack or injector problem. I doubt it your valves. Are you still throwing that cel p0134

[thakid]

Its all good man. And my car does run good. Its not throwing a check engine light. And i did absolutely nothing different besides leave my plug cover off. And im like mad low on gas so that could be why it doesnt have the power it should. And what would you charge to check it out? Thanks

[EFin4Dr]

not trying to be an ass but there are alot of idiot fuckers that work at honda dealerships. not saying youre one of them but that shouldnt be a reason to listen to just you. i work at chapman acura, should he just listen to me??

[thakid]

I am running in circles. So i will listen to anyone right now. hahaha. But my car is up and running. So i dont know what fixed it. hahaha

[RHD EF9]

not trying to be an ass but there are alot of idiot fuckers that work at honda dealerships. not saying youre one of them but that shouldnt be a reason to listen to just you. i work at chapman acura, should he just listen to me??


Fuck yeah he should dog, Naw dude I understand what you're saying. But most the idiot fuckers work at chapman. Not tryin to bash your shop but damn man. Except for Jerry thats a smart ass man. He worked at dobbs forever. Oh and I didn't say he had to listen to just me, I was just fuckin with him when I was talkin shit about listening. My bad if it offended you thakid, but I think you took it the right way.

[RHD EF9]

Idk man. Fill up your tank with some good fuel and good beat the shit outta your car for a bit. clear it out. make a good drive cycle, usually 50 miles, and see what happens. If you get no cels then.... you get no cels lolz. Problem was intermitten. I see that alot

[thakid]

Yeah. Well i havent been driving it at all. So we shall see. But i would like you to still check it out man. If you can. Thanks

[RHD EF9]

Cool, I know Thursday is good for me, I close that day so if you wanna roll by the shop after 6 I can

[thakid]

Where is it at exactly? And thursday i think i work til like 9.

[RHD EF9]

Oh snap not good then. Its on wetmore and automall. right on the corner.

[thakid]

yeah bro. ill let you know if i can go thursday by tonight. Whats the latest you can stay at work?

[EFin4Dr]

lol @ jerry. that fucker is funny. smart man tho no doubt. knows how to get shit done.

[thakid]

doooooods. I want a job at acura or honda. I want to do mechanics. Im not genius at it. I wanna get into it.

[EFin4Dr]

just go in for an application or if you wanna learn some basic stuff take a class or two at pima.

[thakid]

I have not threw a cel yet. But have not been driving it long. Any advice on how to make sure my car doesnt run rich?

[KseriesEK]

maybe the injectors are dirty...or the dizzy?

[thakid]

Anyone got a write up on how to clean injectors? And there is no dizzy on a k series engine.

[IntegraDA]

there is a place local that can sonic clean injectors. get in touch with integra dc2 and he can get you the info you need. its really cheap too. its really the only thorough way to clean an electronic fuel injector. And why does everyone keep saying to check the distributor! AAAH! tells you how much people actually READ the thread before they think! :hithead: stupid n00bs

gahhh fuck people not reading before they post.. It bugs me too. But If you're checkin the distributor, then you might as well replace your piston return springs while you're at it.

[IntegraDA]

yeah....first thing I go for in that scenario...which is usually always the cause of all the problems...is the nut behind the wheel. :(

[thakid]

Integra dc2? How do i find people on this site? haha

[RHD EF9]

Heres how you clean your injectors : Go get MOC injector cleaner and dump it in your gas tank, Good luck.









Atleast thats how we do it at honda lol. We're lazy

[thakid]

Thats not really getting them clean though.

[IntegraDA]

oh just search for users with the search button on the site or browse the tempe/chandler meet thread in the meet section and he's posted there plenty of times. or just go to create a pm and type in his name in the recipient box. and about the 'injector cleaner' additive....it works to an extent...but if there is a piece of dirt or what have you in the injector...chances are, it wont get that out...all the additive does is break down carbon deposits on the nozzle of the injector so it flows better. If you have shit stuck in the injector...it disrupts flow...and they have to be sonically cleaned to break that shit free and then they flow test them to make sure they are in spec.

[Ls91ef]

or you can buy my extra set

[thakid]

haha I got 440. What you got?

[Ls91ef]

but looks like your 440s suck, i forgot you were turbo lol

[thakid]

haha its not even like thats the problem. It "might be" negro. I drove my car all day yesterday. Drives good to me. Hopefully.
