    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 had this problem first at 80,000 and again at 195,000 and last at 205,000. It ended up bending the valves and ruined the engine.

    I had to have my ignition coil and "coil on boots" replaced. 5 months and only 2,000 miles later the ignition coil went bad again. Under warranty thank goodness, but this report doesn't make me hopeful that I won't be back in the shop again soon.
