I got a check engine light after installing my AFE intake and SSTT chip. I had it last season and there were no issues or check engine lights. I have a regular OBDII scanner and the error stated it was a 02 sensor.I tried to erase the code but could not. I tried unplugging the battery and thought it might be because I did the golf tee mod but the check engine light does not go away. I'm not sure if that is an accurate reading. I don't know what the problem is and would appreciate any helpful advice from experienced users. If i can not find a fix then I'll have no choice but to buy a BT scan tool. NOTE: I have had long cranks (4-6 sec) for about 3 months now and I know that my HPFP will die anytime now. I floored my car after I installed the mods and notice that the car all of a suddenly jerked and lost power. I really just want this pump to fail and clear my codes. No more modding for me i have had bad experiences.
