Has anyone had any problems with lack of shut down when brake is applied?
Has anyone had any problems with lack of shut down when brake is applied?
No,, the vehicle is still driving and motor is still turning RPM's I have to stand on the brakes and pop it into neutral to stop the vehicle.... won't shut down...
It happens random maybe once or twice every six months...
The throttle body was replaced by dealer about 5-6 years ago to fix issue Did not make a difference
Always Foot...To the OP, is this with manual throttle control ( foot) or while using cruise control?
OHHH youre saying the engine is still acting like youre giving it gas. never had that happen but it sounds like throttle position sensor issue of some kind.
you can test the tps with a multi meter ( just google testing TPs with multi meter) or try cleaning your throttle body or visual inspecting the shielding of the wires going in to the TB for damage/ brittleness / cracking
(cheap and easy trouble shooting)
It COULD be that:
when the car is on/ engine off it works fine because there is no engine vibration etc
when the engine is on its causing vibration or intermittent / interference of the circuit. or a faulty TB/ wiring
sorry i cant be of more help and good luck!
2007-10 Sport Tracs have electronic throttle control (drive-by-wire) 2001-05 use a mechanical throttle cable.
May want to look into this and other TSB's. Any check engine light or trouble codes?

EDIT- Believe I confused the OP's term "shut down" as stalling. Sounds the opposite where it's not decelerating when braking, even after the throttle body was replaced 5-6 years ago. I'll delete this post if that's the case. Apologies.
