I have an '02 gt, the check engine light came on and i had the code read and it said it needed a cam shaft positing sensor. So i replaced it and had the code cleared. On the ride home the light came back on, so I took it back and had it read agian, and it said the same thing. After a few days it wouldnt start on the frist try, it still wont it takes 2 to 3 trys. I took it to the dealer and they put in a new sensor and then they put in a new computer, but it still hasnt fixed it. The only mod to the car is a cold air intake.
