Seems like it is getting to much fuel as it backfires. What could it possibly be??? I have put new injector seals in it and checked everything else. It is charging 14.1 V so that is good. New OVP and still the same thing. Is there any way to pull a code from this thing? I am not sure where to go from here. Very frustrating.
