Man, I feel your pain! Last summer I had an HEI that would eat a module a week. It kept getting worse. I became an expert at changing them. The HEI was from NAPA. Bought it when my 402 was rebuilt. I exchanged it with them and had the same problem. My friend got tired of this going on when with me, gave me a used HEI and the problem has not reoccurred. The old HEI is now in the core exchange pile. I always thought Modules were either good or bad, either ran on not, but Jodie (GMC Junkie) just had an intermittent problem that she traced to a module.
