Worn or Mis-Indexed Distributor Shaft Can Cause Surging/Bucking on Acceleration on Dodge Ram 1500

Problem Description and Possible Solution

A surging or bucking during acceleration can be caused if the distributor is moved or mis-indexed. This is a result of the cam and crank position sensors being out of synchronization. Wear of the oil pump drive gear can cause similar symptoms because it allows excessive free play in the distributor drive. The distributor drive gear and bushing should be replaced if the rotor tip moves back-and-forth more than 3/16th of an inch when checking drive gear free play.

After the truck runs for 10 to 15 minutes it starts missing and backfiring. You can give it gas but the RPM's don't go up. It has never stalled
