when i turn on the car the wideband innovate A/F gauge spools up to 14.9 and sits there until i tap the gas then it just skips up to 22.4 and sits there and doesnt move at all no matter if i drive give it gas it doesnt move one way or the other. it was working fine for almost a week since i picked it up after installing SC and gauges. i cant find any loose wires or anything. any ideas what this could be?

 

sounds like either:

signal wire from the sensor to the gauge = bad
or
the sensor itself has gone bad
