    There's something wrong with my POS Ford Ka.

    When i'm coming to a halt and push the clutch in, the revs rise up to around 4000 and then just back off.

    The revs rise as i'm changing gear aswell but apart from that it seems perfectly normal.

    Being a complete novice to anything that's related to the technical workings of a motor vehicle, I haven't a clue whats wrong.

    Is it just that the clutch cable is caught against the accelerator cable or is it a dying clutch?

    Thanks :)

    Sounds like either a sticky throttle cable/body or an air leak.

    What happens if you hold the revs at 4k and then back off? Do they stay at 4k for a few seconds?

    edit... Yeah, or the IACV ;)

    Thanks.

    Is that something a novice like me can learn to fix or is it a tricky job?

    The purpose of the Ka if for me to learn about the inner workings of a car :)

    Once i'm at a stop and it's stopped being an arse it seems to be fine :confused:

    I'll confirm later though :)

    Get the Haynes manual out. You can clean out the ICV and Throttle Bodies with carb cleaner. Should do the trick.

    Crankcase hose fracture, ISCV (DEAD if its getting up to 4k), inlet man leak, throttle cable perhaps but you would notice either extra pull or mega hesitation.

    Try cleaning everything, ISCV and throttle body/plates.

    If you cannot move the valve within the ISVC, change.

    Local library?
    Our main one has all the Haynes in the reference section.

    I can afford to buy one, just stating that the book is £15-£20 more than my car ;)
