Cool beans! Either the MPGuino or the AFR gauge will work. The MPGuino will give you lots more information and takes more time to install. The AFR gauge will only tell you when you are in lean-burn, but will be easier to install. Since you have a 1993, you probably have a narrow-band 02 sensor. You need to make sure the AFR gauge is for narrow-band.

I don't know if a WAI will keep it in lean-burn. I suspect the ECU/PCM doesn't take the air temperature into account for lean-burn.
[EDIT: MetroMPG corrects me below]
