Anyone ever had a a/f guage fall off the charts (red side) when the o2 has warmed up at idle? I hooked up the A/f guage in three spots, stepping closer to sensor as I go, no difference.... I hooked an ohm reading up to the o2 and it seems to read fine, but no codes. The car drives well even under boost, and responds well to afc changes . To add to it I have tried two a/f guages just to make sure it wasn't a guage issue. never seen this b4... hooked up a many a/f guages too.

thoughts?
