Default Codes! Car running rough. P1171, P0171, P0136

Hello Everyone! Hoping to get some assistance with a problem that has my 1999 S70 non-turbo stranded:

Symptoms:
  1. Running rough in general.
  2. Bad idle
  3. Black smoke out of exhaust (rich)
  4. Large hesitation to accelerate

Codes:
  • p0136
  • p0171
  • p1171

What I've tried:
  • Replacing MAF
  • Assuring MAF connectors are clean.

Any ideas?
Thanks!
