Ok once again that damn check engine light is back on. Autozone pulled the code and its the same one p1443. I have checked eveything that people have told me to look at and nothing looks wrong. Anyone have anymore help on this one? It looks like I am going to take the stang to the shop on Monday if I cant find the problem this weekend.
i noticed it only comes on when i drive on the highway for 15 minutes or longer but then it gos off
