Default Acts like it wants to die

I have a 96 4x4 blazer that has a hard time starting up and acts like it wants to sputter out all the time. Replaced plugs and wires, and MAP sensor as well as all O2 sensors. It will also run it's self at a high enough idle to accelerate up to 50 mph without touching the throttle sometimes.

Are you throwing any codes? If the idle is bouncing all over it could be a throttle position sensor
