Lots of possibilities here without more info. Have it scanned by someone who actually knows what they are doing and not to just erase the codes. Please report back. I just fought one of these with a 0.02 volt difference in ground potential between the ECM and the battery ground. Your problem may require a knowledgeable technician.
