Fuel injectors test?
 

So my ep3 is having random misfires, I have changed out my spark plugs and checked the ignition coils and all seem ok.
Was thinking of checking if any of my fuel injectors are faulty
Anyone know where locally to test them at for a good price?

What codes are u getting? Did u try switching coils to a different cylinder to see if the misfire moves

yea tryed that and everytime i disconnect one of the coils the engine start to shake so all coils seem to be in working order.

the only thing i havnt changed is the code for a knock sensor, seems i have a bad one. Just havnt heard much of having a misfire from that
