Thanks for the suggestions.
Did some more investigation of the problem, completely tested the AMM output, the automatic idle control valve and the throttle position sensor and everything checked out ok.
I am starting to feel that it is a wiring/electrical problem outside of the components themselves, possibly even a failing car battery (it is fairly old).
I am trying to figure out what is changing between me jostling wires and reving the engine while parked (no symptoms) vs. driving down the block and seeing the problem almost immediatly. Transmission turning, more vibrations, more fuel consumption?? Hmm.. this one has me stumped.
