I have a problem with the corsa, had it in the Vectra before I removed the engine, when accelerating and depressing the clutch pedal to shift up gears the engine rev's increase. the higher the revs when changing gear the higher they go when the clutch pedal is down.
under 1500rpm its fine but by 3000 the revs go up by 1000 rpm.
if I wait 2 seconds before depressing the clutch after letting off the accelerator pedal it doesn't do it.
Courtenay said it maybe the clutch pedal switch? checked this and 12v to ecu from switch when driving, 0v when pedal is depressed. is this correct?
ive tried with switch disconnected, still fault and bridged so constant 12v still has fault.
new throttle pedal stepper motor fitted, new throttle body also.
please help me! 🙁
