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?

That vacuum pressure sounds good to me.

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.
