Originally posted by GregH: Now hold on.. what happens when you close the spark plug gap? preignition or a misfire? If it's missing, and the plugs and wires are relatively new and good quality, I would put a coil on it and keep the gap at 52-56. During cruise, when the computer leans the mixture way down, you'll get a better light with a hotter spark. Lean mixtures are harder to ignite.
Yes I know. I do have new spark plugs and wires. I think it is a weak coil to. The hardest to ignite is hight load at low RPMs
