Hey everyone. I have a 2003 4.6is with 53k. A couple of days ago I noticed my engine started to run a little rough when I am in gear, stopped with foot on the brake. Yesterday the check engine light comes on and then today flashing check engine light comes on. I have to drive 260 miles to get to BMW indy, and I'm a little nervous. Anyone had a flashing check engine light? What does it REALLY mean. Im leaving 10am tomorrow the 18th.

Any input would be useful.

Thanks
