Hi
Got above car in. Car revs up to 4k RPM on its own, flat spots and also breaks down. It now doesn't start, tries but just cuts out.
3 codes left, 2 were 120 and 220. Both relating to throttle. Live data shows the throttle pedal position sensors working fine. No response from Throttle sensors. Moving throttle butterfly by hand shows the tps working through live data.
Actuator test doesn't work throttle motor. Switch ignition off then on allows actuator to open throttle but just snaps closed again. Can't actuate again untill key is cycled off then on again. Working throttle pedal allows you to open throttle till about 90%, go further and it just cuts the power to the motor.
Does this sound like ecu probs? If so, dealer only to code in?
