Yeah... a faulty TPS would mean your throttle is messed up. You should've seen it when it was doing over 4,500 RPM. I didn't think of taking a video since I was moving floormats and restarting the car at every intersection. It would rev right up after a restart. Bobo, appreciate the input. Spearfish, you're still the man.

Oh, by the way, my clutch didn't like this little incident very much.

Could be the TPS. There is a procedure to recalibrate the throttle... I'm sure the service department is going to try that.

Its pretty easy if I remember right - look for the service manuals on the website here. Its a matter of mashing the throttle to 100% and then 0% back and forth, but you need to get it into calibration mode...

I agree with Bobo, sounds like the accelerator pedal position sensor is a viable culprit given these cars are fly by wire throttle.

Section EC (Engine Control System), page 18

ACCELERATOR PEDAL RELEASED POSITION LEARNING
ACCELERATOR PEDAL RELEASED POSITION LEARNING : Description
Accelerator Pedal Released Position Learning is a function of ECM to learn the fully released position of the accelerator pedal by monitoring the accelerator pedal position sensor output signal. It must be performed each time the harness connector of the accelerator pedal position sensor or ECM is disconnected.
