Ok so this is what i replaced. PLugs o2 afm clt air filter and fpr and icv. Car still runs rich but not as bad as it used to. I have s50 injectors and mark d 93octane chip. I did a fuel pressure test and im a bit rich. I was wondering if i could drop in a seta 2.5 bar fuel regulator and it would run ok? anyone? Also if anyone knows where i can get a cheap afpr id like to know.

Anything foul in the wiring that would allow the injectors to stay open? possibility? Fuck if I know how to troubleshoot fuel issues

im thinking one of your injectors is stuck open too.

[e30 gangsta]

really how would you trouble shoot that?

[chuckybob]

pull the injector rail and see if any of the injectors are continuously dripping. test the voltage at each injector plug with the car running (BUT DONT PULL THE ELECTRICAL PLUGS WHILE THE CAR IS RUNNING), it should alternate between ~battery voltage and no continuity. if it doesnt change from battery voltage, then either your multimeter isnt sensitive enough and you need one of those fancy diagnosis machines with the wee sine wave, or the problem is the ecu. if they all check out then pull the injectors and get them bench tested.

Coolant Temp sensor? If the ECU thinks that the coolant is always cold then it will always run rich.
