Thanks for all the support. I have two more questions:

According to MSD, the resistance is suppose to increase in the 0.7 ballast resistor (some sources say up to 1.4 ohms) when the engine is hot. How does that effect my voltage? (Perhaps you already explained this and I did not quite get it?) What would happen if I put in a 1.4 ohms ballast resistor instead of the 0.7, combined with a 1.4 ohms coil and kept the 1.5 ohms "wire resistance"?

The only thing that I changed on the car this year was to a leaner air fuel mixture since I had to high CO. Bubba wrote something that rich air fuel takes less and lean air fuel takes more voltage. Could this affect the "voltage need" in my car?
