1990 4runner 3.0 running rough, throttle hesitating

Hey everyone, just bought a 1990 4runner 3.slo last week. It ran perfect on the way home but the next morning when I tried to start it up it idled at around 1200 at the lowest. punching the gas a little causes it to sputter and almost die and smoke comes out of the exhuast before revving up again. pulled some codes and got 12, cant seem to find what that means. Anyone have any opinions?? this is making me wanna jump into traffic
