I just finished my OBDII swap this week and my car is throwing code P0300 which just says Random/Multiple Cylinder Misfire. I keep on getting that code. It will go away sometimes and then come back and run like crap.
I read on this site that had GM codes listed on it that if you find a random misfire code (P0300), the problem probably is not the ignition system. It's likely a lean fuel mixture caused by a vacuum leak or dirty injectors.
I am already positive that it's not a dirty injector because the injectors in the car I got from Witch Hunter Performance. I am almost positive there are no vacuum leaks too. Could this code lead back to FPR, Fuel Pump or Fuel Filter?
