My marauder has 77K and started doing some unusual things.
Intermittently it would High idle at 1200 and miss on about 2 cylinders, shut it off, and restart and it was fine....an electronic ghost.
After reading up on some posts, I decided it was most likely my coil packs.
So far this has been the fix for the intermittent problem.
Now it idles right, and is glass smooth accelerating.
Too bad the nifty yellow coils are covered!!..LOL
