Was any engine work done to the vehicle, a loose ground can cause this problem. The cam sensor wiring harness can also rub through to ground and cause this problem. If you disconnect the cam sensor harness at the module and read the ac volts across the 2 terminals while idling, it should be about 1V Ac. If not replace the sensor.
