I couldn't agree more. I promise to to give more than a concise update when I solve this problem. I have located some interesting reading about the Bosch KE-5 jetronic fuel injection system at www.Bosch.com.
I plan to use the advise from this thread and other problem solving techniques that I have learned through life (Ford's 8-d), Taguchi, ect. to get to the root of this problem.
