Alright my CEL light is on and its been on for a day or so, took the car to my buddies shop yesterday to see what the code could be. It was a P0300, random cylinder misfire, cleared the code, drove home with the light off and the car running fine. Took my buddy for a spin almost home the light came back on. Talked to Hitech motorsports and asked them what the problem could be and they maybe said the tune that i have. I have ottp stage 2 and their tune. Emailed ott and asked them what it could be and they said to find out what cylinder is misfiring and switch the plug with another plug and do that for the injectors as well. Also, i have noticed that my afr is all over the board. I have another post with the afr question. Anyother ideas that it could be? Tune, etc...
