BEST MECHANIC CAN'T FIND THE PROBLEM

1993 Pontiac Grand Am • 160,000 miles

The car starts up okay, but when the foot touches the accelerator, it stops. The 5-star mechanic in town cannot find the problem - he has replaced computer, the mass air flow, sensor, the fuel pump, the throttle position, the crank sensor. His advice was to take it to someone with more "wiring" know-how. Meanwhile, do you have any suggestions? ANY help would be greatly appreciated!

Is your check engine light on? If so, please have the computer scanned and post the codes here for more assistance.

Meanwhile, try cleaning the throttle body and idle air control solenoid using carb/choke cleaner.
Also, look for vacuum leaks (hoese cracked or disconnected.
