I have a 2007 F150 5.4 and recently it started misfiring, i got a check engine light and it said that i needed a new camshaft position sensor on bank 2. I went ahead and replaced both sensors and am still having the problem. i took it to a mechanic and he told me that when it starts to misfire it is because cylinders 1,3,5 and 7 are cutting out. The thing that confused him is that it only does it when your driving and its warmed up. Anyone else have this problem and know what it is?

 

Part of your issue is misinterpreting the code. There isn't a single code whose description say "Replace XXX". Most codes are circuit faults of different flavors, and the CPS codes are no different. If you post the code we can help you track it down, but you likely have an electrical problem of some flavor.

 

The code is P0345
