2002 pt cruiser. The car idles fine in park and revs up normal. However if the car is in reverse or drive and give it gas the car will stall pretty much every time. Once you do get it to go it drives normal and doesn't stall while driving. Like i said if you put it in gear with your foot on the brake and give it a little gas it will stall. The motor was just installed in this car and from what i was told the spark plugs were changed, i cleaned the idle air control. Not sure what else was done to it.
