Car was running rich but is fine now

So I bought an s13 that was running crazy rich. As in, on start and warm up im in the 10's, regular driving im in the 11's and sitting at a light and afr's are dipping into the 9's. I never really got on it till yesterday when I did a good wot 2-3 gear pull. Now the car is fine. 14-15s regular driving and 12's wot. Kinda going reverse but I wonder what the problem was?

I had a similar issue where my injector orings would seal, then unseal themselves causing the rich running, i say pull/replace all injector orings and see if it doesnt stop.

glad to hear shes running well again, gotta love it!

so....I cleaned/moved the maf to the stock location cause it was ziptied down by the swaybar. I noticed that the maf wires were cut/reattached and i kind of moved them around a bit and afr's went normal. I guess my voltage is getting messed up.
