    We have a 1994 Saturn we purchased new.

    Last year it started having a problem where it
    seemed to hesitate when starting up from a stop,
    and then kind of bucks for a second or two, then
    drives fine. We took it up to the Saturn
    dealership and they did about $600.00 worth of
    repair work( replaced egr valve, cpp solenoid, egr
    solenoid, basic engine analyzer test, replace PCV
    valve, replaced engine air filter, replaced
    serpentine drive belt, clean and decarbon fuel
    system, replaced engine coolant temperature
    sensor). We went on a driving vacation and
    noticed that over a few hundred miles it started
    this hesitation and bucking again.

    We stopped at a Saturn dealership and picked up a
    set of spark plug wires and installed those.
    Seemed a little smoother for awhile and then the
    problem started again after just a couple of
    hundred miles.

    The problem is much more pronounced the hotter the
    outside temperature is. It becomes even more
    pronounced when the air-conditioning gets turned

    Now during the cooler months there is very little
    if any of this hesitation and bucking problem on
    starting from a stop.

    Would very much appreciate some suggestions as to
    what the problem might be. This is my wife's car
    and I hate the idea of her being stranded

    Thank you,

    Bad valve cover gasket? Do you have oil on the spark plugs? The oil could be
    leaking through the gasket onto the spark pulgs, fouling them up.

  3. ....what do the coil towers look like? (just a thought - mine on my 97 get
    corroded and sanding them a bit and putting some new dielectric grease seems
    to help)
