What happens is the signal from the dual-potentiometers disagree. The control computer see this mismatch and tries to get the car home in a 'safe mode'. This typically results in slow performance and some hesitation. There may be some relief by turning off the car and cycling the accelerator many times (trying to knock out the crap in the gap) and then trying to drive.

The right answer is to remove the accelerator assembly and clean the wipers and resistor traces. But this is not a trivial task and Doug had developed a fairly extensive process. It isn't such a hard job, just tedious with a lot of fine points that must be paid attention to.

I've got three failed units to upgrade and one I'm testing in the car (been testing it for three months.) So the next person who needs one, get the one in the car and I'll get the other units reworked and on a testing schedule.
