a few months back i started having a problem with my car cuting up at full throttle that i posted about... just thought I would share my final results because I found them a little odd and it may help someone else in the future. The car was not displaying any check engine light(it does function) and also the only code i got was an egr code(because my sct chip has the egr turned off). My original suspects were the obvious plugs, wires, cap rotor. None helped. Then I started checking sensors Mass air, act, coolant temp, tps, iac, oxygen sens, all seemed ok. Then I tried something on a complete guess and it worked. It was the ignition control module. I had replaced it a year and a half ago but i guess it was failing already. The car would only cut up when it was hot so im guessing that the internal circuitry of the ig control module "opened" when it was getting hot causing the miss. Never got a cylinder misfire.
