I would say its a fuel issue. Like its not getting enough. Im not very familiar with a firebird but if it has a carb i would say it needs rebuilt if it is efi or throttle body then i would say that you need to run some cleaner through it. It just dont sound like its getting enough fuel. Also check the plug wire order. Ive heard where 2 wires were crossed it revved up fine with no load on it. Just some ideas it could be a lot of things also clogged fuel filter.

thanks for your input it is efi and i checked timing it is 30 degrees off if the no 1 is where the chilton manual says it at i put it on dead center and the car ran like ****. i swapped 2 wires around that i thaught i might of got swapped and it backfired and ran really terrible when the car is cold it runs great and once i actually get it going down the road it dont run real bad only when i stop then it acts up i will try the fuel filter next thanks for the help

If the plugs are black the injectors are bad..pretty common.
