If the Check Engine Light/Service Engine Soon light is on or has been on a code is stored in the computer in your car that will indicate where the problem may lay. Stalling or cutting out may be caused by many things, a defective idle air control motor or vacuum leak are the two most likely causes. Rough running could be caused by loss of ignition to a cylinder due to a bad spark plug or ignition coil.
