I know I know, sounds like an ignition problem... but, I just replaced the wires and plugs not even 10,000 miles ago! It's not an all the time thing, when there's no engine load, no jerkiness, under full throttle, jerkiness (misfire or no fire?), and in slight acceleration circumstances, SOMETIMES it's there. I sprayed water on the wires tonight to see if I could see any signs of bad wires, but nothing. In park or N it doesn't happen. So what do you guys think.... Coils??? How much are those things and how do you know if they are toast or not?
