Question type: Maintenance & Repair

I have a 1991 Nissan 240sx with an
sr20det in it. I have a prosport wideband
air fuel gauge and it keeps reading around
18.2-20.1 but my cars running fine not hot
at all  and doesn't seem like it's running
that lean. Any ideas why this is happening?

If you are not getting a check engine light and the engine is running good I would have the gauge checked, that lean should turn on the check engine light and it is not so I think your meter may be out of calibration.
