2003 Ford Mustang 3.8L Misfire
Posted to Ford Driveability on 8/12/2016 19 Replies

My daughter's car, intermittently starts misfiring going down the highway, AC cuts out as soon as it starts, she can pull over and restart the car and it runs fine. Very intermittent. I am leaning toward replacing the computer, but hate to throw parts at it.
