For the last couple of years, I've had static on the FM stations on the radio. Frequency directly related to engine RPMs.
As near as I can tell, the block ground is good.
It's done this with 2 different radios, and the current deck is grounded back to the battery (also has a noise filter on the 20A positive lead.)
After I got back from Moab, the noise had mysteriously disappeared. And the distributor bushings started squeaking. I put in a new distributor today, along with a new set of Mopar Performance plug wires. BTW, plugs are Champion Truck plugs, new a year ago. After putting in the new distributor and wires, the FM noise is back.
As near as I can tell, it's got to have something to do with the distributor.
Any suggestions?
