Emissions thread!!!

Alright I took me ej this second time and still didn't pass. First reading were HC(1.12) , CO(24.38), NOX(3.02) So I put a new dizzy, wires, spark plugs, and starter, and now it read this HC (1.08), CO (15.87), NOX(4.17). What could it be? They told me to check the timing. Anything else should I check for? Am running 91 and didnt do the alcohol myth. So am ???? Any info would help. Thanks.

Definetly check the timing and then check it again! Don't run 91 octane you only need to run 87. If you haven't changed your PCV valve then remove it and shake it, if it doesn't rattle then you need to replace it, that will help a lot(personal experience) regardless of what other people say! Oil change, coolant flush, new air filters! GL

But see the weird thing is that after I changed the dizzy, starter, wires and spark plugs. It didn't wanna run so good. it was running kinda rich so I thought I try 91. So this fucker ran better.... After that, it start over heating so I took out the thermis... fine. It was running great. Ide was normal. It didn't shake or anything. After they ran it again @ emmisions it start to run the same as it was b4. Also my sister took it to the store and put 87 and it sounds like a suba again. Lol I'll check the PVC and the timing. Thanks man.

try to check your o2 sensors or the cat convertor cause what the denaturalized alchol does it warms up the cat when the o2 sensors are supposed to do that so check that

check the cat. your co reading tells you the efficiency of your cat. it looks like your cat has failed due to the car running poorly before for a long time. replace it and it will pass most likely.

denatured alcohol doesnt do this.
it just burns very very clean thus helping to reduce the emissions of the engine.

since then have you put it back in the engine? cause even though you remove the thermostat, yes it does cool it down. However, it makes the car over cool and tends to make the vehicle run richer than its supposed to..

Oh alright so i guess i have to put it back then. Cause the car starts and it ides kinda high for about 15 seconds. Then goes down back to normal. But how about the nox?

ok your runinng a little warmer plug....Bosch is a brannd for Nissan and some Ford and GM models, yeah they have made plugs for Imports, however i recommend even though its pricey but if you want to run better, go with the stock replacement plugs...NGK actually make the car run a few degrees cooler....because NOX is caused by increased temperature in the exhaust gases..
