    a sick mk4 astra

    right guys/gals my sister inlaws astra is sick at the moment,its a 1.4 16v on a 52 plate and it keeps cutting out on her.
    lastnight when she started it up the revs jumped up and down and it sounded really rough.

    any ideas as to what could be causing it

    if its not them try cleanign the throttle body and check the air filter isn't too clogged

    Hi,

    That sounds exactly like a vacuum hose pipe is disconnected.

    Check all the small rubber hoses for any splits at the ends and check they're all connected.

    Regards

    My money is on the egr valve. Give it a good going over with carb cleaner and give the throttle body a good clean too whilst ur at it.

    Both should be spotless and free of carbon deposits when ur finished.

    Keep up posted
