backfiring alot

RE: backfiring alot
If the O2 are reading weird readings they are making it run rich/lean depeneding on what fuel/air map the ecu decides to use. if it is running lean which it sounds like it is not then it can hurt it if it is running rich like it sounds its not as bad but you may just want to take the O2 out and clean it put it back in.
Edit: sorry i think i missed this did you say you have no O2 sensors? there should be 2 of them one at jpipe and one after where the cat would be. If they are missing your ecu might not be mixing fuel/air right.
