If there aren't any CEL's, a datalog might yield some info. If you can't datalog and there aren't any codes, do an ECU reset and if it comes back to its old self, your part-throttle long term fuel is probably way out.

You may have picked up another code or two, get it scanned to be sure or check with K-pro if you have a laptop. If it's just the secondary O2, then go with the datalog or reset.

I would just check the usual stuff: Condition of hoses, connections, anything obvious. Double-check any installs you did recently. Have you tried to datalog this phomenon?
