On nearly all cars on the road today the engine idle speed is computer controlled. These vehicles are being recalled because the idle may be to low as a result of a sensor failure causing the computer to operate in the fail-safe (limp home) mode. In the limp home mode, the computer will not properly adjust for variations in the engine idle speed. As a result the engine can stall unexpectedly at idle or when coming to a stop. The sensor causing this concern is the accelerator pedal position sensor. Dealers will replace the accelerator pedal assembly and reprogram the engine control module to correct this concern.
