    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.

    Took car in to have it smogged. When technician hooked it up to test, the engine light came on. He checked it out on the diagnostic and said one cylinder was misfiring and it would cost about $2,000 just to get into the engine not to mention fixing it.

    What a shame. We had just had both recalls done. We've maintained the car meticulously since we bought it new.
