My check engine light started to come on. It would go out on its own. Now it also occ flashes. I had the spark plugs and wires replaced and then coil pack replaced. It came on again when the car was idling in driveway for several minutes as well as at a stop light for a period of time. When I accelerate the flashing light promptly goes back out or back to solid. Now it is pretty much staying on again, alternating w short periods of flashing (mostly when sitting at a light, etc). The codes were showing misfires in cylinders. Oddly, now my airbag light is staying on. I am in the process of trading my car in so I don't need the inconvenience of lights on or costly repairs. Obviously, the engine light reflecting a problem will impact the value at trade-in. The local mechanic is at a bit of a loss.

When a check engine light is flashing...the car is misfiring. This can cause major problems...I don't recommend continuing to drive it. I do recommend taking it to a service shop
Hope this helps

You might have a bad connection at the coil pack,,,wiring...common issue.. or a low compression engine.
