Ok the car was driven a good eight plus hours ran fine sat over night came back next night to try to go out to eat car wouldnt start. Have had the battery check oud igntion coil checked out, new spark plugs no luck, then decide to rent a diagnostics scanner and it came up with the error code P0340 but we have replaces the cam position sensor and it still comes up with the same error and still wont start, any suggestions would be helpful please and thank you+
