94 firebird 3.4 5 spd, intake, stock otherwise. It runs fine at idle but as soon as i give it any gas it sputters and occasionally backfires. I was told the throttle control sensor, i just changed it and no luck. I know this could be many different things but im new to these cars and wondering if there is a common problem that i might not know of. Not throwing any SES codes, any help or suggestions where to start would be greatly appreciated. thanks.
