So Jltalons 1997 Trans Am is back together and computer has a basic street tune. car starts right up and runs good except when on the gas. It just constantly backfires. plugs and wires were all double checked and were fine. Had an issue with the opti-spark though and tonight we tore it all down and straightened the pins for the connection. We put it all back together and then does the same thing. Heads,Cam,Injectors were all upgraded…

Any help would be great. thanks
