Stepping on the accelerator pedal? otfl

Sorry I couldn't help myself......I can't tell you why, but it is linked to the computer somehow. Maybe you should check all the grounds. C4's are pretty picky about there electrical supply.

On yours it's controlled by a electronic sensor that is gear driven in the tail shaft of the transmission!! 4 things come to mind,plastic gear on output shaft,(possible but not likely)plastic gear on sensor,(again possible but usually not) Sensor,(happens most likely) or Bad connection at the sensor plug! (Yep,I've found that on a few!)

PS Oh yeah, could be a connection in the switching from Metric to English in the dash!!

Stick in a paper clip scanner, and see if you get a H72 module 4 (or 9)... Some codes will NOT light up SES.

VSS is a purple and a gold wire coming off the harness on the drivers side just about 10" from the ECM, near the ex manifold. The connector is right near there.
