    4.9 Code 41 Saga Continues!!!

    So I replaced the cam sensor for the 3rd time and now it has a completely different attitude. The code 41 has become intermitent, and it idle, it is on, when I rev it up, it goes off, and if I rev too high for too long, the engine cuts off!! What the hell??

    Inspect the internal distributor wiring carefully, looking for fraying. What you are looking for is an intermittent short to ground.

    If you visually inspected for any fraying that could intermittently cause a short to ground while still exhibiting the correct ohms and you flexed the wires while testing to verify that there isn't an internal break that only intermittently causes an open, this is certainly an enigma.
