    Idle Control Valve - faulty?

    I took out my ICV to see if that was perhaps a cause of my idle problem.

    After cleaning it out and spraying WD40 I have noticed that the plunger does not move out, no matter how hard I pull. The plunger is positioned at the length specified in the Haynes manual.

    Also, I read somewhere that you could test it by plugging it in and sitching the ignition on (not starting it though) and the plunger would move - mines didn't.

    Does this sound like it needs replaced?

    It's an Astra x16szr 8V by the way.

    common fault on these engines - i went through 3 in about 3 yrs

    if u do get a replacement - only buy genuine Delphi ones

    best supplier I know is VPW on ebay

    heres the part for your motor if u decide to bite the bullet: http://cgi.ebay.co.uk/Vauxhall-Idle-...item2a01b541a6


    cheaper ones are quite frankly shite!!!

    the idle valves are very stiff and care should be taken when trying to push in the plunger as it can overstress and damage the motor, then the valve is knackered. GeordieBandits advice is spot on, if you suspect the valve then it is best to change it for a delphi unit, they are around £30. incidentally testing the plunger as above will not always work as the plunger will only move when the ECU sends it a signal which depends on other engine sensor outputs at the time of the test
