I know it wasn't written with our cars in mind but I tried it anyway. The result was about 0.67 volts. Grounding it seemed to make it idle better, unfortunatly it was only a temporary connection and a test drive was impossible. What do you guys think of this?

 

Sounds like a recipe for disaster-trying an electrical fix meant for a particular problem on an import car on an LT1, but who knows?
