I own a 1986 Chevy S-10 Blazer. I keep burning up a component inside my ECM. My truck runs fine until the ECM burns up, usually after a day after installation. Then the truck misses throughout the speed range, and backfires occasionally. After the ECM burns up, I check my timing and the timing is way off. Resetting the timing fixes the backfire problem but it continues to miss random cylinders. I have new spark plugs and wires and a relatively new distributer. I have uploaded a picture to show which chip is burning up, in hopes that somebody has the schematics to determine what this chip controls. Something has got to be shorting out somewhere.
