I have a 2000 Mazda b4000 4x4. Lately it has been almost choking itself out.

If I try to go at a steady speed it will start choking. When it happens I pin the gas and it will stop till I try to get speed or go at a steady speed. I feel it on the gas. It doesn't do it all the time but is becoming more and more. I have cleaned my mass air flow sensor, changed my vacuum hose. Does this sound like a fuel/air problem or a possible throttle problem? The gear shifting(automatic)is a little rough lately too.
