Help w Bank 1 Sterm high only??
Just as stated, Bank 1 STerm Count goes to 150, while the LTerm stays at 130 at idle.
Bank 2 everything is fine Sterm Count 128, and LTerm Count 128.
This is only occuring at idle, with an idle PE tune. My lm-1 is on bank 1, after the o2, and it is reading 13.8 at idle. What can cause the STerm to be reading so high? There are no exhaust leaks present. Can it be a misadjusted intake valve?

Are you running an aftermarket TB? Some aftermarket TB's don't have the "air feed hole" that the stock TB has to supply air directly to the intake ports for idling. This has been known to cause a mismatch in blocks. Try doing a search on this topic.
