Re: Fiesta rev problem



did he mean a clutch pedal position switch?  some of these also have a multi
wired reverse/gear switch, what does that do?

Re: Fiesta rev problem



ECU has switches both on the clutch pedal and brake pedal which allows it to
better control engine idle characteristics during changing gear and also
braking. When the switch goes faulty or pops out of its locating bracket you
either get stalling when coming to a halt, or a stuck high idle which takes
ages to return to ~850rpm.

Re: Fiesta rev problem



When?, during idle?, maybe Idle Control Valve.
