i recently got a 03 4x4 and it was running perfect. A couple of days after having it I went and tested the 4x4 on a easy trail that a car could make. the next morning the check engine light was on and it was shifting hard. a friend checked the codes and they were about throttle position alignment or something to that effect. i've checked the forums and still am unsure of what i can do to fix it other than going to dealership. any help?
