Rich fuel mixture

2002 Cadillac Escalade 6.0L V8. So my exhaust always smells like fuel and then I was trying to test something so I unplugged the MAF sensor then wen to start it and it doesn’t run without the MAF sensor being plugged in. If I unplug the MAF sensor while it’s running it will bark run. Also when pressing the guess the accelerator can be very jerk where if I press the accelerator about halfway it acts as if I floored the pedal and it will take off. Sometimes if I press the pedal almost all the way down it will accelerate but slowly climbs. So is it a MAF or MAP sensor giving false readings to the computer or what. I read that if the MAP sensor faulty it can cause jerky acceleration and I also read that if a MAF sensor is faulty it can a rich fuel mixture.
