Rough idle, Maf problem?

[97rangerdanger]

Hey guys, Ive been trying to figure this out for a while now. I have a 97 2.3l with a rough idle/low rpms (stalls out idling until warmed up but still very sluggish at low rpms). If I reset the ecu it runs much better but starts throwing the codes again in about 30 miles. After around 2000 rpms it starts to run better. It is throwing a maf code and two o2 sensor codes (running rich). If I unplug the maf there is no difference in how the engine runs. I replaced the maf on a whim a few months ago but it didn't fix the problem. I checked the voltage on the wires going to the maf- they are all good, 0.9v at idle, 2v at 4000 rpm. My guesses are vacuum leak or or bad plugs. I looked around and didn't see any unplugged vacuum lines. Any ideas?

What are the codes... theres about 50 possible codes for o2 sensors and maf sensor and they all mean something different.
