I just sold my tuner so i cant check anything and im starting to think that its my pcm fuc**** up..the car runs amazing until i go WOT a few times and then itll run like pure ****

 

I personally have never seen a computer cause lean codes. That doesnt mean its impossible but I assure you its highly improbable.

I cant tell you how many people come into the parts department at my dealership to buy pcms and end up trying to return them (no return on electrical parts) because it didnt fix their problem.

Id put money on you having another problem.

 

if my coils or fuel injector connectors was shortin out would that cause it? or maybe a fouled plug?

 

A fouled plug would cause neither, but both would cause a fouled plug.

A hanging injector would be easily spotted by a completely fuel soaked plug.

A bad coil would be spotted by a similar looking plug, but maybe with more carbon deposits on it.

Swap coils if you suspect a bad one, but dont be suprised if you find a misfire on the original cylinder as well as the new one.

 

so if you had to guess what would you say would be my problem since it runs good at first and then ****ty after going WOT a couple times
