Just rolled 40K and over the past two weeks I have had a engine miss or cough when I am at speeds over 50 mph. Happened twice on the way home from work today. Kind of felt like it was a loss of fuel rather than a loss of spark. It was just for a second and the car gave a quick jerk and then continued running just fine. Anyone have a similar problem? I am going to try and stop tomorrow and see if the auto parts store can pull a code.
