    My 93 Saturn currently is starting, and then going out with a loud cough.
    This morning while driving it, it sounded and felt like the engine was
    going in and out, winding up and down. It is also idling very high.
    The local Saturn dealership usually rips me pretty good. Before I have it
    towed there, any ideas on what it could be?

    Mileage? Maintenance history? Any previous symptoms? (Did this start
    running rough a year ago, poorer fuel mileage, etc?)

    Given your description of what is happening and the age, without knowing any
    more, I'd say it needs a good tune up and any required maintenance as the
    place to begin...

    Thanks Bob. The mileage is 91,955. No previous problems, except that it
    idles high at start up, then dies down in a few seconds to normal. At my
    last oil change they recommended a valve cover gasket. Did not have the
    funds at the time. Thanks for the imput. I'm just looking for a general
    idea so that I sound like somone they can't rip off for a thousand bucks
    when all I need is a plug or something.

  4. Has it been viberating or missing, are the plugs good,wires,if this is true
    i would say fuel system ,fuel injetor problems likely , second may be Idle
    control or IAC ,third may be Throtle Position Sensor! Just guessing here !

    Thanks Justa! No virations..plugs and wires are good as far as I know. I
    was also thinking it might be fuel injector..given that upon start up it
    quits like it ran out of gas. The car stays on, but the engine sputters
    out. You may be on to something. Sounds expensive, but at least I have an
    idea now. Thanks much.

    Lots of previous discussion on cleaning the throttle body and plate if you
    search the newsgroup archives. It could very easily be the problem and a
    simple cleaning of the Throttle and Air Intake Servo (AIS) could solve your
    problem. You still don't indicate when the plugs, plug wires, air filter,
    fuel filter, PCV were last replaced. Also, at that age there could be
    brittle or cracked vacuum hoses that if leaking would also cause the high

    lastly, there are a number of sensors and the EGR that also have a history
    of requiring maintenance, but before you do anything there, make sure the
    other items noted above are known good first.

    Good luck!

    Check the coolant temp sensor. It sends temp info to the computer that
    controls the amount of fuel the engine gets as it is warming up. Had mine
    fail, and the computer thought the engine was always hot, and did not enrich
    the fuel for the cold start up. Simple, cheap and easy to replace.

    For simple diagnostics, if the car runs better and better as you manage to
    get the engine to warm up, this becomes a high suspect. Be careful not to
    replace the sensor for the temp gauge, they are different.

    My symptoms were, almost would not start when cold outside. Would sort of
    catch every now and then. Once caught, just barley sputters, and required
    much open throttle to keep it running. Kept on stalling. Persisted with
    starting and as engine slowly got warmer, the engine slowly stared to run
    better. Eventually ran perfectly. Once cooled off, back to square one.
    Replaced coolant temp sensor - bingo, all better.
