Ok, my roomate has a 89 Pontiac Firebird Formula with a 305 TPI and having some problems. When accelerating it doesn't pull really lacks power, around 3000rpm it sputters, feels like engine is working harder than it should. Acceleration is really really slow. Fuel pressure is ok, we just changed the fuel filter and its okay now. What else should we check.
