I went thru a lot of this and it ended up being my lower intake gasket. On mine the gasket was blown out around cylinder 2 and 4 causing an internal vacuum leak which was taking my long term fuel trims up at idle.
If it was your distributor being off you would get code 1345
Did this start before or after changing injectors?
Here's a photo of what was collapsed on the intake gasket
