Question about 2000 Pontiac Firebird
Have you ran a diagnotic check to see what codes are coming up?
Throwing parts at the problem will get expensive. It will also ruin other parts (Like your catalytic converter), when your engine is misfiring and not running properly. Your vehicle is an OBDII system, fix the problems in the order they appear (then clear, run and recheck)...meaning, one problem can cause another and so on. Fixing one problem may correct the other ones too.
You may get lucky with the shotgun approach, but usually not.
Run a diagnostic test, at least you'll know where to start looking for the problem.

Sounds like a bad injector.
I'd have them ohm tested.
