My Service Engine Soon light just came on yesterday while I was driving from work yesterday. I wasn't driving the car hard and the car only has 12k miles on it. The car runs good and has no problems; damn light just popped on out of nowhere! I am wondering if any one else has experienced this. I changed the oil about two months ago. Could this just be a way so Ford can get money from there customers to have the car serviced when nothing is wrong with it? LOL! What if I disconnect the battery will it reset the computer, or should I have it checked out?:shrug:
