1991 mazda b2600 not running right

Ok so I aquired this "mini" truck from a junk yard near here for super cheap. I drove it for awhile but now it will start but dies imediately unless you play with the throttle. Once it levels out it runs fine %50 of the time. It is fuel injected (did not know these had that factory option) and I have already checked fuel pump, fuel filter, spark plugs, spark plug wires, and relays...what could be wrong besides it being a junk yard dog?

Loose wire or air/fuel sensor going bad. I had one in a delivery truck. The sensor was loose in the air intake housing near the front and would do the same thing..

I was finaly able to narrow it down..going from sensor to sensor and found that mazda is really proud of their mass air flow sensors...400 bucks...guess what...yep thats my problem after unplugging it the truck runs better but still needs that part to run correctly
