2000 4×4 Isuzu Trooper 3.8 Liter. When it starts up it idles fine
QUESTION:
I own a 2000 4×4 Isuzu Trooper 3.8 Liter. When it starts up it idles fine, however, when you put it in gear the RPM goes up and you have to keep your foot on the brake pedal because it feels like it wants to go and move fast. Very unusual to experience. Not sure if this is a sensor problem or not. The transmission was replaced or rebuilt in April 2007 with 120,000 miles. Any idea?
ANSWER:
I looked up technical bulletins on your vehicle and it appears there have been problems with the Accelerator Position Sensor. Beyond that it will require some diagnostics by a good technician to determine the exact cause.
