no throttle response
we have a s300 turbo diesel. our car is equipped with drive by wire accelerator pedal. we went europe for a month and we return, the car start yet if we depress the accelerator pedal, nothing happens. no matter how long we depress the accelerator pedal, engine doesn't response, only idle. we replaced the accelerator pedal sensor & throttle actuator (located beside injection pump) yet the problem remains. we checked all the electrical wiring related to engine ECM, all is fine. what seems to be the problem? am i beyond help?
