Pontiac Grand Prix GTP Problems

Intake Manifold Gasket May Leak Coolant or Engine Oil

The intake manifold gasket may develop and external engine oil or coolant leak. In some cases, an internal coolant leak may occur causing coolant to mix with the engine oil. Running the engine with a coolant/oil mix may result in engine damage. Replacing the intake manifold gasket should correct this issue.

Stalling Due to Mass Air Flow or Crankshaft Position Sensor Failure

The mass air flow or crankshaft position sensor may fail causing the engine to intermittently stall. It may be necessary for the engine to cool down before it will restart.

Engine Stall Or No Start Condition

The fuel pump may fail causing engine to stall and not restart.

Bought this car with 22,000 miles in 2004. I love my car, would never trade it in, unless I could get another one!! Starting to need some repairs (150,000) but nothing out of the ordinary. I hope this one runs forever!!! My sons are constantly arguing who will get the car when I can no longer drive, LOL!
