Hey all, I have an innovative wideband LM-1 in my car. Here is the problem though, at idle it stays around 14.7 but when i am crusing it bounces all the way from 14.0-15.2 all the time. Also when i do a free air cal the sensor reads 20.9. Is this the sensor going bad or something like a bad ground? I am stumped. Any help would be great, thanks!!!

 

Nevermind, normal for AFR to fluctuate under part throttle load. Thanks!

 

My LC1 does the same. No problem.
