CEL Due to Short Term Fuel Trim - Running Rich 850 1997

I'm stumped. Got a CEL due to misfires a couple weeks ago so I changed all the plugs and reset the light.

Yesterday I got another CEL but this time the codes were for running rich. The short term fuel trim was cut all the way back to where it set off the light.

Any ideas of where to look and what to look for? No O2 sensor codes.
Could it be the MAF? How do I check the MAF for proper readings?
Any other ideas?
