Having problems with your Pontiac Firebird ?
Why does my 99 firebird run good and then when I give it gas it just wants to sputter and no power?also from a dead stop in reverse no power.Most of the time though it runs fine then it happens again??
Your coil pack is bad same car same problem fixed it with the coil pack
Do you get any check engine light? If so, read the code(s) and pursue to repairs. The symptoms sound like fuel pressure problems or maybe water in the fuel. Put some gas guard or similar in the tank and drive for a while to work it through. With luck, that may get you running again. Change the fuel filter.
