One other thing to check/try. Is ran into this problem more then one time. Once with a new cap a rotor Is the rotor was bad even for being new. It would miss under a load only. I put the old stuff back and all was fine. So i took the cap and rotor back for a different one and Installed it and All was fine. If a small hair line crack is there Even if you can't see can raise all kinda Hair pulling. So this is just somethings else to Look for That may not be the problem But ya never know It always seems to be the Real simple this some times. Hope this helps }[oooooo]
