Hi,

I have to ask. What wasn't working? Did you get no throttle response? You indicated the cat stopped working. Please explain.

As far as the throttle pedal, that could be a few things. By chance, was the check engine light on when the engine was running?

There is also a chance the vehicle was in limp mode. You may want to consider cleaning the throttle body. It may help. Take a look through this link for directions and help to identify possible causes:

Let me know.

It was strange, there were no check engine lights. The car was in drive, but when i pressed on the gas pedal the car did not move and then started to roll in reverse. when i took my food off the gas and then when i turned the car off and back on it was normal again.

Hi,

There could be an issue starting with the throttle control circuits. However, it certainly sounds like you were in limp mode. Were you able to review the link I attached? Also, has it happened again? Since there were no codes, my thoughts (or theory) are the APP may be the issue. If it didn't signal to accelerate, the computer doesn't know the difference. But again, that is a theory.

Let me know.

Take care,

Joe

My girlfriend was the one driving it, and i was wrong, the check engine light did come on when it happened, she said all the check lights came on and then when she turned it off and turned it back on the car was fine.

The car is pretty old and has been sitting for a while before we bought it. so I'm hoping that getting the throttle body cleaned, will help.

Hi,

If all the lights came on, that was likely the result of the engine stalling. I wonder if that is what happened. It's just a thought.

Ask her if that is a possibility.

Take care of yourself,
