Hey guys i went to start my car up tonight and I haven't driven it since tuesday. As I went to start it up all the lights inside the car and the gauges started flickering and the car started up very rough and then the CEL came on. I have an AA drop in filter, resonator delete, and an auto couture exhaust. None of the o2 sensors have been touched so i don't know what could cause this. If anyone as any suggestions please tell me. Btw my car is running up on 65k miles. Thanks guys
