Just a slow Idle when at operating temp, slow speed surging once in a while. I just pulled it off today, carefully opened the attached TA wiring harness cover some of the wires are toast (the inner smaller color coded wires) however the black wires are fine!
Tomorrow I'll try splicing new wiring put everything back together and give it a try. BTW my cruise worked fine. I found and replaced a very brittle small vacume line it ran from the back of the engine intake, under intake runners to the front of the engine to the drivers side fender. I also bought a Sears multimeter complete with duty cycle, I'll try my luck with diagnosing ox sensors.
