hello, can anyone help me out? I have a 6.0l with a mild cam and 317 heads. I was running a fitech system and one day while driving down the freeway it started running odd when I pulled over the engine was running supper rough. when I tried to restart it the engine backfired and died. I replaced the cam sensor and the crank sensor no change. I then swapped over to a P01 ecu and put a stock file in. After turning off VATS and the usual stuff I'm getting the same results. Today I unplugged the cam sensor and it started but was running really rough and would not idle. Any ides ?
