1993 Pontiac Grand Prix mileage: 79,000. My car won't idle and it stalls. The service engine soon light comes on. I got the diagnostic code off the car, it flashed code 33. I was wondering if you could give me a hint on what could be wrong.

Code 33 is a map sensor problem. Check the engine for vacuum leaks. Check the exhaust for blockage (catalytic converter). The map sensor may be faulty.
