Service Engine Light 2000 Chevrolet Tahoe
My service engine soon light is flashing. About a flash per second. When at a stop, the car idles very rough almost to the point where the car shakes a little. Any thought of what that could be???

You have a misfire. That's the only reason a engine light flashes. Don't drive your truck long like this
