The distributor may develop internal faults. This can cause a rough running engine or stalling condition, the Check Engine Light may or may not illuminate. Our technicians tell us that the distributor should be overhauled or replaced to correct this concern.

worked fine for 270k miles then had to replace the distributor due to a loud squealing noise coming from the distributor and a resulting erratic idle and stalling. 30k later with a new MSD distributor same thing.
