Bank 2 are the post cat 02 sensors so there are a few thinsg that could be going on:
# Damaged HO2S
# Malfunctioning ECT
# High fuel pressure
# Damaged exhaust manifold
# Damaged catalytic converter
# Oil contamination
# Cylinder misfiring
# Downstream HO2S wires improperly connected
# Damaged exhaust system pipe
# Damaged muffler/tailpipe assembly
# Retarded spark timing
This will be a tough one to troubleshoot without access to complete pinpoint diag steps. It might be worth paying the lincoln shhop diag fee to have the isolate the problem and then decide if you want to DIY.
