Full lean reading under any small amount of throttle

My UEGO 30-4110 recently started acting up.  It appears normal at idle (~14.7)  but as soon as I get on the fuel (even a little bit) it goes to lean limit (---).  My wideband is placed before the cat where the 2 headers merge.  I have 2 different factory AFRs (one on each head) which read normally.  I don't see any sort of exhaust leak.  Is this just a broken sensor? anything I can do before replacing the sensor?
