I just bought a 94 Pontiac Firebird for 1 grand, knowing it had engine troubles, but I was hoping to fix it up. It is a 5.7L V8 engine. It starts right up, and idle seems fine. But when I push on the gas, the acceleration is horrible. At one point I was at a red light, I rev up to around 6k rpms, it barely moves, and I see white smoke coming out of the exhaust. It does get going, it is just really slow. I am thinking it has a blown head gasket, but I haven't had a chance to check the oil yet. Are there any other things that could be wrong? other details are 06 inspection sticker, tires seem worn. seller reported initially that it ran and drove great, am i missing something?
