Went ahead and changed plug wires because they looked like crap... Truck runs better but still idles rougher than normal and still the CEL at idling RPM's... Bought plugs and may change them right away but anyone else have an idea? By the way its a 5.2L v8.
Pull the distributor cap off and wipe out with towel. Spray wd40 in the cap and reinstall. My 88 ramcharger did the same exact thing.
