The previous owner had made some modifications and I bought it with the misfire. I have replaced lots of things to try and fix it. any advice? it has code for random misfire, cylinder 2 misfire, and system too lean. it also has a lot of hesitation when accelerating. I am wondering if the Cold air intake could be causing this since it is still on stock fuel system and no tuning was done. the CAI has a Diameter of 2.75 in and my throttle body has a diameter of 2.5 in if that would make a difference
Replaced:
MAF
TPS
cleaned throttle body
Exhaust system
Oxygen sensor
spark plugs
ran fuel injector cleaner through
tested ignition coils and ECU, both work fine
