Car wil start after initial high RPM it will drop to 1200 and will erratically climb to 1500 RPM and drop to 1200 RPM again several times until (my guess) will warm up then only does it occacionaly. If place on gear (reverse or drive) it willl accelerate and stall (because if the emergency brake or the brake pedal is not hold it will drive on) Throttle position sensor has been tested in acordance with the manual the ohm values are good and the adjustment is also good.

hey it sounds like you are having the same problem my uncle is having. Did you happen to find out why it was idling so high?
