2002 Pontiac Grand Prix Gt can be started with no key and idles and runs roughly.?

Question

Can this be do to the security system. Not sure of the history of the vehicle (stolen or attempted). How would this be fixed or is it worthwhile to try and do so.

Answer 1

obviously there is a problem with you igniting switch and for the rough idling i would get a engine diagnose done since this could be a number of reason's.
