    My Saturn engine dies more and more often. It happened starting around one
    year ago when I waited for a traffic light. I had to restart it. And then,
    the engine dies more and more often. Usually, it happened when I made a
    turn and waited for a traffic light. These days, even during driving on
    highway normally, the engine died sometimes. However, I can always succeed
    in restarting the car (sometimes I had to turn the key several times).

    A mechanic checked my car, replace the four starter plugs and fuel filter.
    The problem wasn't fixed. I knew that catalytic converter of my car was
    also broken. The mechanic told me it could be the problem of "catalytic
    converter". But I am wondering "catalytic converter" can cause engine die
    during driving.

    I do greatly appreciate for any advices or possible solutions to this

    Thank you very much in advance.

    If there were a "Saturn FAQ," this would be one of the top few entries.
    If you do a Google groups search (http://groups.google.com/) against this
    newsgroup (rec.auto.makers.saturn), you'll find many, many articles dealing
    with engines dying and/or revving low.
    IIRC, Coolant Temperature Sensor and fuel problems (for example bad gas,
    bad fuel pump) can cause these symptoms. Hopefully, others with better
    memory and/ or more experience than I will happen along and provide more
    useful information.
    Good luck!

    Well, it seems to me there are many possible cases. I will try some in this
    weekend and let you know how's going.

    I'm coming back to report the result. I fixed the problem which was caused
    by EGR valve failure. I tried to clean it but after a while, it failed
    again so at last I bought a new one and then everything was perfect.

    Thank everyone here. I got many useful advices.

    Good luck.
