P0366 I Recently bought a 2012 astra sri, the eml came on with code P0366 cam position sensor. The previous owner has left a receipt in the car confirming that the cam position sensor had been replaced. Is it possible that the other sensor is failing also? The car runs OK but is a bit gutless and my wife has told me failed to start a few times with her. She has turned off and it then starts OK. Any help much appreciated
