Randomly, once every few drives, while I am idling and idles rough. If I give it a little bit of gas, the problem goes away. This has been ongoing for sometime. It keeps throwing two camshaft error codes. I’ve had it checked over by two shops, and they tell me they can’t find anything wrong. Anyone have any ideas?

09 5.4

P0346 and P0341 keep coming up, and only occasionally seem to put the check engine light on.

Which model year? The 5.4 and 3.5 turbo were both offered in the 3rd gens.
