Acceleration Control System Mercury Grand Marquis IV

Torque Specifications

Torque Specifications

The throttle is controlled by the accelerator cable which is connected to the accelerator pedal and shaft. All vehicles are equipped with either memory, or non-memory adjustable accelerator and brake pedals.

1. The accelerator pedal and shaft should travel smoothly from the idle to the wide-open throttle (WOT) positions. Hesitation on return and/or prevention of return to the idle position must not occur.
2. Surrounding components such as wiring, hoses, sound insulator and floor covering must not contact the sliding inner member of the accelerator cable or the accelerator pedal and shaft.
3. The sliding inner member accelerator cable should not be lubricated and is not serviceable.

Inspection and Verification

Note. All vehicles are equipped with either memory, or non-memory accelerator and brake pedals. For additional information on diagnosing and testing the adjustable pedal system, refer to BRAKE SYSTEM - GENERAL INFORMATION .

Note. Care should be exercised when performing service on or around the accelerator pedal linkage and controls.

1. Inspect the accelerator pedal and shaft and attaching linkage for damage or distortion which would bind or limit accelerator travel.
2. Inspect the accelerator cable for kinks or fraying which may cause binding.
3. Inspect the engine idle speed adjustment to make sure of correct idle speed specification after any accelerator linkage adjustment or repair.
4. Inspect throttle body for excessive wear or damage.
