    Advice Needed Engine Erratic Idle and No Power. (Corsa b xe)

    Hi guys i bought a corsa xe a few days ago since then given it a new, gearbox and clutch. i took it out and all was fine untill suddenly the revs started bouncing up and down and the power disappears (as in it wont move). Any idea's what could cause this?

    Thanks guys.

    Actual engine rev's or the tachometer? Could be a crank sender.
    I'd start by checking all the connections are still sound and no wires are caught or damaged and all earths are good.
    It may be that you didn't fully tighten or connect something that has now come adrift?

    actual engine revs. i have checked the wiring etc and it all seems to be ok. i was thinking could it be a faulty sensor and if so any idea which one?

    not sure,but mine was running bad and cleaning the idle control valve worked for me,
    plus i changed the coolant temp sensor when it was running rough another time as it was the cheapest sensor to change and that worked.
    might also be worth checking all your earths and other wiring incase you disturbed anything whilst working on your car.
