so anyways my car was cranking over earlier kept stalling out unsure why then the next time i went to crank it over a P0340 code popped up and started making this odd knock noise that sounds like its coming from under my valve cover? anyone know what would be going on? It says in ecm cam angle sensor circuit malfunction. Just wonder if anyone has had a issue like this or if they know what it could possibly be before i go out and spend 200$ on a cam angle sensor.
