Ignition Timing
On all models, ignition timing is controlled by Powertrain Control Module (PCM). Ignition timing is nonadjustable. DO NOT attempt to adjust ignition timing by rotating distributor.
NOTE:
On Dakota 3.9L, 5.2L and 5.9L, Durango, Ram Pickup, Ram Van and Ram Wagon, if distributor is rotated, fuel system synchronization will be changed. If distributor is removed or rotated, check fuel system synchronization. See procedures under FUEL SYSTEM SYNCHRONIZATION under FUEL SYSTEM.
