    While driving, I can feel my car "putter", I step on the gas pedal and all the gauges drop down. It takes about 3 times of turning my car back on & pressing the gas pedal before the car will stay on and move. We took it to a mechanic and the engine light was reading a misfire. they changed the spark plugs, and the car is still doing it. they said their only other thought was the coil packs.

    If other people are having this problem, maybe this should be added to the long list of RECALLS!!!!!!

    Same problem, many trips to dealer and unsuccessful repair. Went to junkyard and purchased used ignition coils and installed myself and it fixed the problem for a time. Eventually, the problem returned

    Parked it for the night, it was fine...woke up the next morning to it misfiring. Put in injector cleaner, chaned boots, plugs, and coil. Also chaned out fuel filter. Next step is ignition coil. Only code coming up is a random misfire code. Still in the process of repairs. I have a 2006 Saturn ion 2 with 71350 miles.

    I have three coil packs in the last 8 months. I paid for first the rest were no charge replacements. Any idea why they keep going bad?
