Driving without EGR valve hooked up

Discussion in 'General Motoring' started by the_brewmaster, Jul 9, 2004.

  1. I have a 1992 Saturn SL2 and I just put in an order for an EGR valve but it
    won't be in until next Wednesday. The old valve is stuck open and does
    not create enough vacuum to keep the car running while I put it into gear.
    It drives fine when I disconnect and plug the vacuum hose running from
    the solenoid to the valve, but my question is if driving without the EGR
    valve will negatively effect (ruin) any other systems in my car? What
    does the valve do besides reduce emissions?

    Admittedly I haven't looked at an egr valve in over a decade but in the old
    days you could clean them with some carburator spray and work them back and
    forth into they worked again. I take it that doesn't do it any more?

    It may set a code but you it should be fine between now and when its
    fixed. Be sure to block the other end that comes form the exhaust as

    You should be fine with the vacuum line plugged. I have attempted to clean out
    my EGR on my '92 with no luck. I soaked the pintle area in carb cleaner, TB
    cleaner and still the pintle would not seat properly. My parts guy at the
    dealer was told that oven cleaner is supposed to work well.

    Finally I broke down and spent the $76 at Saturn for one. NAPA wanted $73.

    While my EGR was disconnected, the only time it would throw a code was after
    about 15 minutes of highway driving. Once you got off the highway, you could
    turn the engine off and the light would go out after restarting.

    If it runs fine with the vacuum hose disconnected, then the valve is not
    stuck. The control TO the valve is malfunctioning.
