Default LC-1 actin crazy, worked for one day, now shows min and max

hooked up a new lc-1 and it worked that night, readin normal afr's after it was calibrated per directions. next day all it will do is bounce around from min to max readings 7-20 or whatever why its runnin.

re checked all the wires and its all clean and good.. soldered n ----. the grounds and diagnostic led and button are all on the same soldered crimp ring. the sensor is not in the bottom of the pipe or nothing, basicly i fallowed directions anyoen got any ideas :1

maybe do another free air calibration and see how it works afterwords.
was it a brand new o2 sensor?

awsome, i never heard anything bad about the lc-1 untill i bought one.
i havent installed it yet, but it kind of makes me second guess the good deal i got on it.

LC-1 are annoying but they aren't innaccurate.

Describe your plug readings vs wideband readings.
