Shot Wideband Sensor?

[Loewen21]

Hey guys so i installed my DynoJet wideband a little while ago and ever since install it has given my weird readings. It will read fine on anything from 14-18 at cruise and idle and such but any time it seems it should be reading between 10-14 it will just stop at fourteen. But it seems at times when it goes really rich it will bounce all the way down to 10. Basically it wont read anything between 10 and 14. Is this a sign of a shot sensor or is there something else im looking for? Thanks.

P.S. I should mention that the unit is used so that could explain the sensor being shot potentially.

Do you have any exhaust leaks? That will throw it off a lot.

Typically bad sensors will start reading excessively lean. Possibly a calibration issue?

I'm thinking thats not the problem because it reads fine between 14-18 but goes bad once it gets under fourteen. Just holds there. Ill recheck calibration but i think its pretty good.
