Is there no alternative to the ICM? (Page 2/2) fierogt28 DEC 26, 11:33 PM Vintage-Nut is totally correct about the rebuild method. GM / AC Delco parts only. No mixing up brands. That’s the way to go. phonedawgz DEC 29, 11:07 PM Why haven't you replaced the ignition coil. Does your tach flutter when you are at a deep throttle position at low RPM? If so your ignition coil may have compromised insulation allowing secondary high voltage shocking the ICM to death. reinhart JAN 15, 07:20 PM Problem is even the "high quality" ones are made in the same chinese factory as the "low quality" ones. Only difference is just the brand name. Not saying that is your problem but I wouldn't be surprised if the one you claim is "high quality" is made alongside the "cheapo" one. GodSend JAN 25, 10:15 AM I had a similar problem back in the day. Go for a spirited run at night, park somewhere real dark, and check to see if the bottom plate the ICM mounts to on the distributor is glowing hot. Mine was. Turns out the inner shaft on the distributor was binding, heating everything up, and cooking the ICMs. I suppose you could just feel the bottom of the distributor, but be careful, mind was blistering hot.
