Hey guys I am having this really weird lean issue where it only happens when I let my car back fire or crackle. I am not fully modded or anything here is my list of what I have done:
stock k24a4 with a cat back straight pipe and a cold air intake.
I have been having a lean issue for almost a year now and I have replaced spark plugs, both 02 sensors, MAP, and a MAF and it still runs the same. It has a rough idle but doesn't stall, with ac on the performance is terrible with rougher idle and engine hesitation, at full throttle the car will stutter after 60mph. My guess is the fuel pump or the Idle air control valve but I would like some input to this so I am not just wasting my money anymore on this.
