Terry,

The throttle position switch may be a good portion of your problem. It should show infinite resistance when closed (no foot on the pedal and pedal stomped). With a gap between 0.20" and 0.40" (when you just touch the pedal) it should drop to 0. This can be confused for all manner of other problems.

I tried disconnecting the O2 sensor yesterday morning on my way to work. As advertised it did solve the stumble problem but several other anomolies cropped up like fluctuating RPM's at what should have been a constant 2200 to 2400 RPM and an idle speed that went down the toilet when it was fully warm. I reconnected it when I went to lunch. We're dealing with a system here -- you can't just remove part of it without effecting another. The Digijet seems more like a biological system than an electro-mechanical one though.

I'm going on a parts hunt for the VW wire replacement fix somebody posted yesterday (I've got that printed and stashed in my day planner). A couple of people have posted something about it and the symptoms sound right.

<< The only thing I haven't messed with is the throttle positioning switch, although, I did put my multimeter to it and it doesn't show one iota of continuity, open closed or in between. This may be my problem, and I will replace that also, just to add to the process of elimination factor. Electronic fuel injection-----Phooey!!! However, I will also try the disconnect the oxy sensor, trick tomorrow morning, just to see what happens. This vehicle gets worse MPG than my full sized 86 Blazer, with a cranked up LT-1 350!!

Later,
