...had a very rough idle at times, symptoms same as Hudson66, checked ALL sorts of stuff, previous owner has said new plug wires last fall (and they looked new) so didn't check them, finally clued in Mon AM driving one of the kids to school and the radio was making ominous popping sounds, lifted the hood and could actually hear one of the plug wires arcing (hence the radio interference). Decided to bite the bullet and put in a whole new set of plug wires, could not believe the difference! Runs like the proverbial top, still stinging from the dealer price for the OEM wires , $265 Cdn (or about $180 US). Lesson learned: look for the obvious stuff first, don't assume anything.
