    Hiya

    Bit of an old lady this one i know, but still needs fixing like any other car.

    C16SE 8v multipoint inj astra. Stopped idling when cold and sometimes difficult start. No fault codes and live data all ok. Replaced the idle motor as it was stuck solid (my thinking was it was stuck in the hot engine idle position but not able to open to allow for a fast idle when cold). All seemed ok for a few days then fault came back, no idle when cold, also seems to do it now on warm engine too. Removed idle motor and tested using diag equipment, moves fine. Now its running ok. Also gas checked, all ok. No air leaks.

    It doesnt seem to be controlling the idle speed when running because the diag machine can move the motor in and out fine on functional tests, but if i screw the motor in a little by hand and refit and run the engine it idles at a very high revs and doesnt try to come down.

    Any ideas people???
