I have a 2005 sxt it blew the head gasket. Replaced it and it fired right up but have driving it about 5 miles it started spitting and sputtering and through a code cam/crank sensor. First change the cam sensor. Here again drove it for a little over 7 miles and again spitting and sputtering again then it died just as I got into my driveway and would not start back up and through the same code so I changed the crank sensor but still will not start. it will turn over and every once in awhile acts like it want to start but won't. When I got to drive it it had plenty of power and I know the timing is not off.
