What does cover on evo coil look like?
Don’t know what your cover on your coil looks like, but on my Dyna it was a sheet metal cover with a couple of half-moon cutouts that the plug wires came through. The sheet metal had actually cut through the insulation on the boot allowing the coil to periodically fire to ground on one plug.
Why does my missing plug on my Evo not work?
Especially under a heavy load, like riding up a hill. If you power through this missing, it starts going well at higher revs, but still misses a bit. The plugs look relatively good, but the electrodes get white and the engine gets hot like it’s too lean.
What to do if your Evo battery goes bad?
While you’re at it make sure all your carb seals are not leaking air. It seems to me that you may not have battery voltage at the primary side of the ignition coil or the coil may be bad check the resistans on the coil. And check the spark plug and spark plug cables.
Why is the voes not working on my Evo?
Now I get no response when I spray around the intake mounting points. The VOES seems to be working because the engine slows down when the hose is removed (low vacuum so it switches to the other ignition curve), and it switches at 6psi with my vacuum pump.

Why does my Evo keep missing the CARB?
It starts fine (kick only) and idles well, usually it even runs fine if you are using very little throttle, although I seem to feel a little surging even then. When you go to give it some throttle though, it starts spitting back through the carb and missing. Especially under a heavy load, like riding up a hill.
