Dynojet wideband going coocoo After 3 years of faithful service, my dynojet wideband (guage) is going haywire.
When I go WOT, it goes real rich and then pegs on ultra lean (18). Then it stays there untill 10 seconds after I lt off and reads normally.
It is not tune related, the live scan says all is within good parameters.
Now is it the sensor itself?
Can it be just replaced? or a whole new guage has to be bought.
Could it be dirty and with what could i clean it? gas?

Have you checked the gauge output against what the WBC is seeing through the USB interface? If they are both reading the same, it's time for a new sensor. If the WBC is reading correctly, something must be wacky with the gauge. The dynojet WBC sensor has a different wiring connector from standard bosch LSU4 sensors, but you can splice your old connector onto a new sensor (I did this on my dynojet wideband & it works fine).
