Help needed
I have a 2007 Ford F-150 5.4l v8
Codes
P0012 int cam position timing over ret bank 1
P0022 int cam position timing over ret bank 2
P0300 random Missfire detected
P0316 engine misfire detected on start up
P0340 cam position sensor curcuit fault
P0345 cmp sensor a circuit problem bank 2
Starts rough, idles rough and stalls occur often when start, after it runs for 5 minutes and sometimes dint starts at all. I replaced spark plugs, coils, cam shaft sensors and had oil changes done and. No effect.

If it's running worse, then I would be looking into timing/phasers. Broken chain guides and loose chains can cause the valve timing to be off more than the phasers can compensate for. Your codes state that the cam timing is off and it will misfire if it is.
