Article 00-25-4 is being republished as part of a consolidated 7.3L diagnostic aid booklet and to update the calibration table.

ISSUE:

Some vehicles may exhibit an engine buck, surge, or jerk (also known as hitching/hesitation) while the speed control is active through all engine temperatures. This may be caused by the calibration and strategy of the Powertrain Control Module (PCM).

ACTION:

Reprogram the PCM. Refer to the following PCM Calibration Information Chart for details.

NOTE:IF THERE IS A BUCK/SURGE CONDITION WHILE NOT USING THE SPEED CONTROL, OR DURING ENGINE WARM-UP, REPROGRAMMING THE PCM WILL NOT CORRECT THE CONDITION.
