1995 Pontiac Bonneville Owner Comments

1995 Pontiac Bonneville engine would suddenly shut off anytime, anywhere, at any speed, usually during warmer weather, leaving the driver with no power brakes nor power steering. The car usually would not start for at least 30 minutes, stranding the driver and passengers. After spending alot of time and money trying to diagnose the problem, we replaced a "functioning" yet defective tps (throttle positioning sensor) that did not malfunction to the point of registering a code on the computer. The problem has not recurred.
