Car shuts off after I take foot off gas pedal

Car shuts off after I take foot off gas pedal?

Hello and welcome to Just answer.com, Super mechanic here. About your vehicle.

There may be a problem with the idle air control circuit but you will want to make sure that the throttle body and idle air passages are clean.

You may want to do a throttle body cleaning on it. You can pick up some throttle body cleaner in most any part stores. You can follow the directions on the can but you will want to make sure that you give it a few shots with the throttle plate closed, so that the cleaner can get into the idle air passages.

Of course, you will want to make sure there are no vacuum leaks and that there is not any un-metered air that is entering into the intake, and that the air intake hose is on good and free of any cracks, thanks

We recently replaced a vaccum booster on the driver side. Could this be related to that?
That would normally raise the engine idle, if it were leaking. You may also want to make sure that it's not one of the ones that need a PCM recalibration as per service bulletin or recall.
