Get it checked out before its toooo late.....wideband lambda etc:
Has the afr meter ever read correct ? have you done any work on the car recently ?

No question - get i checked!

...however, if it never leave the read zone - you should get the afr meter calibrated. If you drive and maintain speed the afr led meter will make a light show quite often when the computer is ajusting the mixture. If you never se that the afr led meter is not correctly installed, does not have proper ground connection or need calibration.

If you have a presition power supply you could try to apply 0.95 volt to the afr led meter and it should read a little rich mixture.

If the afr meter is showing rich at 0.95 volt you could have a defect O2 sensor, but guess it is the one you have tried to switch - not the MAF sensor which is in your air intake.
