Help !! Since this is my son's car and he is over seas he has had me bring his car to the shop to have 3:73 gear's , short tube headers and an off road x-pipe installed. I took his car out for some exercise today and got about 2 miles down the road before it quit. I connected the computer and it was throwing a cam shaft positioning sensor code, i replaced that and it cleared, but it still will not run. When i try and start it, it will rev up to about 1500 and then die again, when it does try and rn it is really rough like the timing is off. Does any one have any ideas, i would like to have this fixed by the time he comes off deployement, thank you.
