What causes engine to stall when coming to a stop?
The engine stalls when coming to a stop or on deceleration. The engine runs normally otherwise. If the engine runs poorly you should address that symptom first. A problem in the idle speed control system or transmission is the usual cause of this symptom. Almost all modern vehicles utilize computer controlled idle speed control.
Why does intermittent stalling occur in a car?
One of the more unusual causes of intermittent stalling we’ve heard about is a defective vehicle speed sensor. When the vehicle stops moving, the PCM may not engage the idle speed motor (carbureted engines) or idle air bypass motor (fuel injected engines) so the engine will idle normally.
What to do if your car stalls while idling?
If air can’t go through the air ports when needed, the engine may stall when you reach a stop or while the engine is idling. Locate the IAC around the throttle body. Unplug the IAC solenoid electrical connector. Remove the solenoid from the throttle body.
What causes a car to stall at 40 miles per hour?
The stalling typically occurs while decelerating at speeds below 40 miles per hour. The problem is caused by the calibration of the idle air control valve and evaporative emissions system.

What causes intermittent stalling on a Ford Escape?
Ford has also issued a recall (04S13) for 2001-2003 Ford Escape sport utility vehicles with 3.0L V6 engines for an intermittent stalling problem. The stalling typically occurs while decelerating at speeds below 40 miles per hour. The problem is caused by the calibration of the idle air control valve and evaporative emissions system.
