Has anyone had this problem or have an idea about what else to try? There is a misfire on Cylinder 1 with the engine light flashing. I have replaced the spark plugs and spark plug wires. I have also put fuel injector cleaner into the car. However, the engine is still running extremely rough. (Almost seems to be shaking like a diesel car and the light is of course still on.) I would appreciate any suggestions!

Could be the coil pak. That's where I would go next. Seems a bit odd for it to be going out on such a newer model but, stranger things have been known to happen. Hope that helps.
