I just bought a Plymouth Neon for a work vehicle.
After two days of driving it I have a problem. When I turn the ignition off the engine keeps running. All electrical things....AC, Radio, etc. turn off but the engine still runs even after removing the key from the ignition.

Could be the engine is too hot or the idle speed is too high and throttle plate is not fully closing creating a run-on/dieseling.
