    Well, brought the car into an opel/vauxall dealership yesterday to get
    the fault codes read. 10 f/c showed up. The guy there then erased them
    and started the engine again to see which code appeared first. It was
    the idle control valve and Rpm(Crank Sensor) that appeared first. I
    bought both the idle control valve -which was a little black thing
    (when i opened the old one later it consisted of a motor with a screw
    shaft which turned a cogged wheel to push a plunger thing in/out which
    would press against the idle lever on the trottle body lever -is this
    an idle stepper motor or an idle control valve?)and the crank sensor.
    The crank sensor worked cause now the car dosen't cut out when it the
    car gets warm but the ICV didn't make any odds. The car is still
    ticking erratic.
    Interestingly when i had a closer look at the ICV, i noticed it didn't
    make contact with the Throttle lever at all and didn't plunge in/out,
    therefore there must be no volts getting to it. So while i had the old
    one open i put current through it to see if it worked and it did. this
    makes me think that idle control fault is more to do with the wiring or
    the source of volts to it rather then the unit itself- wasted ?150 on
    an idle control valve.Could this mean a fried ECu- what lies between
    the ICV and ECu, fuses, relays etc or could the volts not be coming
    through because of another fault in some other sensor.
    the technician also told me that the car is OBD compliant but i have my
    doubts, i read somewhere that a sign of OBD complinant is when the
    engine checklight dashlight is an outline rather than filled in, as it
    is on my Corsa.

    a 2000 1.0 12V corsa should be OBD compliant..

    s
    o thus you can do the paperclip trick to read codes.

    well that should show a fault code then.
    sounds like it might be ecu.

    i'll look on autodata tomoorow eve and tell you the ecu pin to monitor.

    never got a reply. Sent them a follow up. never got a replt to that
    either. What a great service..
    Anyways heres my findings so far.

    The paperclip does not work on 00 corsa. There is a 16 pin connecor
    which dosen't look like an OBD connector but is( its the same as the
    one on that site REcommended earlier for the paperclip method. On the
    00 corsa there is no pin 5 or 6 which one i cant remember.
    The fuel system is Motronic 5.1.1 and is Eobd compliant
    There is no idle contol valve which can be cleaned, its the type which
    consists of a little motor which connects to a part of the throttle
    linkage (kinda like pressing the accelatoer slightly to stop cutting
    out)


    On my car there is no power coming to this motor which could be my
    problem. I m getting this checked out next.
    Mike, can you get me the pin out for this on the ECu whenever you get a
    chance.

    nice 3 points yesterday.

    Check out this site and let me know what you think. Seems to be getting
    good reviews

    at last i got my motor fixed.
    its running sweet now.
    The problem was twofold. The Crankshaft sensor was knackered which
    caused the car to cut out when warm and the Wiring loom to the Idle
    control was broken


    thanks for you help guys
