Buy a remanufactured distributor or better yet a GOOD MSD distributor unit, wear and tolerances are allowing it to have sloppy rotor control, and timing. This causing random misfires. Regards Not really dire, lol

I bought a brand new one, and it is dire due to the fact i have almost thrown eveything including the kitchen sink at it
