Re: 92 camaro rs 5.0 tbi car runs but backfires and wont pick up speed right
I have seen this happen for different reasons. 1. timing is out of whack 2. fuel pump is weak 3 cat converter is on its last leg.
you may also want to pull the codes as five7kid said to confirm.

thanx guys..............will look into that, i have a update on the proble, i messed with the timeing but did not have a light to use, the car does not back fire now runs a lil better, but still with probs, now when i accelerat it has real bad lag out of first but when it goes into second gear it does alot better pickup almost normal, but while im accelerating i noticed the ses light comes on but as soon as i let up off the gas it goes off checked the codes and it is not showing any bad codes any idea should i have it put on a machen and have it checked that way or can the cats cause this thanx
----------
one other thing i noticed mine has the oh so warnderfull tbi, how hard would it be to chance to carb and a price range would be good im on a low buget, but the main concern is i notice im leakeing fuel right where the injectors are i mean the fuel pressure reaglator is setting it is leaking where it goes into the throtle body thanx

Code 33 is not "everything ok". Sounds like you've got a MAP sensor problem to fix.
A MAP sensor fault would cause all of the things you're talking about.
