My car will shut off when I let off of the gas pedal. Why?
What is your question?
I drive an 02 Pontiac Bonneville with a 3.8 engine (not supercharged). When you turn the key the car will start but will instantly die unless you press down on the gas pedal. If you press the gas pedal down the car will run but will die when you let off of the gas. I have been told that it is my fuel filter, my fuel pump, my catalytic converter, and my Bank 2 O2 sensor. What could this be?
RepairPal Certified shops can diagnose and repair your 2002 Pontiac Bonneville. They provide transparent pricing with a minimum 12-month or 12,000-mile warranty on repairs and services.
This could be an issue with the throttle position sensor or throttle body. Could be fuel related as well but only a hands-on inspection at a shop can tell you the answer for sure. You don't want to order and replaced parts without a complete diagnosis or you will waste a lot of money.Use this link to find a good shop near you.
