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.

Distributor started having a rattling noise. I replaced the rotor and top, didn't help. Also generated lots of ignition noise in the radio. Local dealer repaired.
