    astra 1.6 16v 2001 stalling on braking

    Hi,
    I've recently had a problem with my astra in that if I'm driving at 40+ mph and brake to slow down at roundabouts and change gear then the rpm drops from over 2000 to below 750 and the engine stalls. The car will then start up again once you turn the key while coasting. I've had the car serviced and a brand new thottle body fitted which didn't cure the problem. I was then advised to get an ecu update which I had done at a vauxhall dealer. They also cleaned the egr valve which they found to be stuck shut as well. I've drove the car once since then and the car seems to be driving ok with no stalling.
    Therefore how does the egr valve cause the car to stall when braking and changing gear????. And also is it possible to blank off the egr valve on a 2001 1.6 16v????.
    Any help would be appreciated
    Thanks

    If your dealers worth the money they would of updated the ECU, which the latest version has the fix for the EGR valve so that it doesn't cause problems any more.

    Does it happen all the time or only once warm?

    I'd try cleaning the throttle body out!
    Its a jam thing

    astra 1.6 16v 2001 stalling on braking

    Hi, Thanks for the replies,
    The stalling problem would happen all the time whether the car engine was cold or warm. I had a new throttle body fitted on 07/07/07 which didn't solve the problem.
    The vauxhall dealer has actually upgraded the ecu on 11/07/07 and they cleaned the egr valve which had closed shut. They then put it back in the car. The stalling problem has now gone but i'm sure the car feels like there is a slight judder now when driving.
    Cheers

    If the ECU was updated using the latest file then the ECU is programmed to no longer use the EGR valve. If they cleaned it and put it back together then you shouldn't be experiencing a problem to be honest.

    Try cleaning the throttle body out which if you do a search you will eventually find my thread about me cleaning my throttle body out including pictures, which should be of some use. The next thing I would do is replace the engine coolant temperature sensor as this can lead to stalling/overfueling problems when warm "usually". £15 from Vauxhall. Next I'd find a member in my area who has the same engine and change over the DIS, Distributorless Iginition System which replace the old style coil pack and leads setup and it plugs direct onto the spark plugs themselves.

    Hope that helps

    Thanks for your reply Jam
    Would I actually need to clean out the throttle body because it is brand new?

    How much did a new egr and ecu cost please, as this also seems to be my problem.

    Hi,
    The garage took the egr valve out of the car, cleaned it, and put it back in again and then updated the software on the ecu all for £50.

    would this be the same cure needed for mine? It does not stall while driving tho. Once stopped it seems to drop in revs and then rise as if i was reving it up. It has stalled once or twice when stopped but has not done it while driving. i have had the throttle housing stripped and cleaned, but it has not cured the problem.

    Oh i think i might of posted in the wrong area as mine is a 2.0 sri
