99 Mountaineer Cam Synchronizer P1309 code

I recently replaced the cam synchronizer in my 99 Mountaineer and I used the alignment tool but set the synchronizer at the same position it was in originally at which was situated in the 5:30 or 5:45 degree position. The truck runs good but I get a P1309 misfire code and except for poor gas mileage and some lack of power at the top end and some pinging. When I experimented with the cam position at the next tooth of the gear, it was set at about 6:30 or 6:45. As I stated the truck runs good but I wonder if I should have set the synchronizer to the 6:30 position and what would that do to the performance of my Mountaineer and would it hurt the engine to try it? Does anyone have any thoughts or ideas on this. Could use some help. Thanks! :confused:
