My 1990 pontiac grand prix le will start and idle fine but when you give it gas and it gets up to 2000 rpm it bogs out and dies! hELp! what can it be?


it could be either a clogged catalytic converter, or a mass air flow sensor. One way to check the cat is to let the car run for about 10 minutes and look at the underside of the car to see if anything is glowing, or check it after a very short drive. To check the Mass airflow sensor locate it and unplug it while the car is running and see if it clears up.

Possible blown head gasket. Check the oil to see if there is water in it. When it starts, does water or steam come out of the exhaust pipe? Those are 2 signs of a blown head gasket.
