    i read time and time again that people go, ye, need to clean the idle air valve out....well to a degree yes...

    but u are not sorting the problem.....it will just do the same

    what happens on the vectra is the breather junction where the pipe goes on to the os (as stood at front of car) of throttle body clogs up , so forcing the idle air valve to take the brunt of all the crap and makin that lovely top hose go soggy and dead...

    so, if u want to solve the fault....and p.s i havent changed one idle air valve on a vectra in ages, and i havent seen one back..and they all drove lovely after the following work done..you guys seem to be spending money like mad..and two months down the line..its faulty again...

    so here goes

    remove air inlet pipe....
    remove tps switch wiring plug, and idle air plug
    mark the top coolant pipr at back of throttle body, so u know where to put back..easy done to forget...remove them both
    remove throttle cable, the little clip has to come off first
    theres two breather pipes....remove both
    undo both fuel pipes at their unions...17mm
    now undo the four ten mm nuts and remove the throttle body
    remove the idle air valve now, look after gasket and its ok to reuse inlet to throttle body gasket again..
    get toothbrush, and carb cleaner...operate flap, and clean all edges of butterfly up so there is not one bit of crap around it esp at its edges...
    now the fault thats makin her cut out...get a paperclip, open up....clena out the blocked very small breather piepway thats underneath the buttefly to one side..very small...always blocked and so not breathing.
    spray carb cleaner throo it too..
    now clean out your idle air with carb cleaner well
    rebuild as stripped....gaskets will be fine to resue unless damged...

    the car will drive like a completely different one, no jerkeness, and smooth as hell..and the idle air will go on workin fine for ages...and idle beaut

    u can also do the flame trap mod which is good..the black box on front crank breather and replace the top pipe from cam cover to air ind pipe if mushy/split

    this how is to save u lot a bomb.....so i hope it helps u out.

    I have read the answer but missed the question. My problem is that my Vectra SRi cuts out for no reason when I slow up or stop at a junction. It seems worse after I have been driving then stoped and restarted. It does not happen every time but when it does it keeps doing it for abourt half an hour and is then fine again. Of course when it happens it means you lose power stearing so it could be dangerous The problem seems to be getting worse I used to have the same problem with my Cavalier Sri and never got to the cause. Please can you help Kevin

    no offence but this is why i didnt bother helpin out any more on this forum...

    try reading the first post..jeees it aint hard

    CLEANING OUT THE IDLE AIR VALVE WILL ONLY CURE FOR SHORT PERIOD....it is not curing the fault.....
    THE THROTTLE BODY NEEDS CLEANING OUT....INPARTICULAR THE BLOCKED PIPEWAY IN THE THROTTLE BODY..

    unblocking that pipeway will remove all cutting out, and the nice jerkyness that u get... be as smooth as after doin the above

    the flametrap mod is a box you put on the front black breather pipe that you see on the front of the cam cover....you cut a bit out of the pipe...chuck the box in, jubilee clip on to each rubber pipe remaining. cleaning the rubber pipe out is a good idea..but no one will i suspect...this mod stops the hose gunking up and helps breathing

    Hey guys...

    Chris is a really knowledgeable chap and ought to be listened to. This is good advice from an ex-Vx employee who has a fair bit of experience in the trade.

    My Omega needs the same treatment, it's not as though it's hard to do!

    Ian.
