1995 Ford Mustang mileage: 106,000.Engine is idling at 2000-3000 rpm.I was hoping this was just an intermittent problem, I have attempted to reset the computer by disconnecting the battery for about ten minutes.After driving a short distance, the idle will sometimes correct itself, at other times the "Check Engine" light will come on.The car runs fine other than the fast idle.This problem came on suddenly shortly after having the engine cleaned.Mere coincidence or could it be related?

1995 and later model cars will not clear the computer by disconnecting the battery.Cleaning the engine may be the cause of your problem.All the sensors and controllers are very sensitive to moisture and corroded connections, which will give faulty readings to the computer. Now that your car has dried out, scanning the computer for fault codes which should pinpoint your problem.
