Car will not run smoothly when engine light is not on but as long as light is on runs great.

As of late it is hard to start. Have changed cam shaft sensor and crank shaft sensor. A code P0325 comes up on knock sensor. Is there a diagram showing the wiring for the knock sensor

see pic on how to test wires shold not run close to plug wires as this will set the knock sensor off also if there is a heavy knock in engine that may be your problem. this can also be a bad prom which are not available or ecm. the prom plugs into pcm.
