I noticed when changing my cap and rotors a few months ago that the inside of the distributor was coated in a redish powder. I remember reading awhile back that if this occurs, the distributor is going bad. So, I realize the distributor has gone bad, but how does a bad dist. affect an engine?? I have been trying to diagnose a rough idle problem for a while now and am wondering if a bad dist. would cause a rough, misfiring idle prob?
Could someone name a few things that a bad dist. could do to an engine.
