Hey guys, just put a new engine in my truck. Put a 4.6l 3v in place of my 4.6l 2v. I have almost all the kinks worked out, but one problem. It has two codes, one for Bank 1(too lean) and one for bank 2 (too rich) I don't even know that the cause could be, maybe timing? I put cam phaser locks in, maybe I wasn't careful enough and the timing chain skipped a link?

Thanks guys.

 

Anybody have a clue? Thanks!
