    The coil tested fine, can the ignition module do that. Fires sometimes, sometimes not. Please help.

    Check the cap on the top of the rear plug, mine came loose and I would get intermittent fire on that cylinder.
    When it lost power the check engine light would come on as well. How old are the plug wires? Dirty crank position sensor? Just a few thoughts.

    Thanks for the tips, didn’t seem to help. Guy down the street gave me a ignition module to try out. It’s been raining since, I have to work outside so I have to wait until it clears up. Will update when I get it done.
