Default Still running rich.

Hey guys. I have a 91 s13 dual cam. 142k miles. So my car went into limp mode. I replaced the maf and it pulled out of limp mode. So I decided to replace my plugs. no change. It still misses and is running rich. What do you guys think it could be? I'm stumped.

I'm confused as to this maf situation
You replaced your maf sensor, and it came out of limp mode
But you replaced your spark plugs and problem still persists?
Did you put the old maf back and realize it may be dirty, or bad?

No cel or codes. My maf was bad. So I replaced it as well as my plugs. It still runs rich. Just not in limp mode.

Constant idle is about 500. Doesn't fluctuate. I don't know about iacv. And rich on both
