The RPM gauge on my 1992 Ford Explorer has suddenly started acting up. It just start flipping back and forth between 1.5K and 3.5K when I am at a stop sign. There is no noticeable change in idle speed. The engine does not seem to be reving up.... It will also "flip out" when i am driving down the road.
Anyone have a suggesstion????
I had this problem when I had my ignition wires arcing out, at night, you might look at your wires and see if they are jumping across it will look like lightning under your hood. I hope this helps. Gary
I had this problem. The dealer replaced the tachometer and all was fine afterwards.
I'll check that out.
Thanks for the tip

Might have to resort to that. Thanks for the info.
