dont bother with the o2 sensor guy above is a douch, speed sensor sounds like the issue, the other is most likey the FIV ( fast idle valve) its on the back of the intake manifold next to the throttle body, remove the cover on top 2 phillip screws and tighten down the white plastic looking thing inside... idle should come back down, thats the most likley cause... as for the smoking....its a b21a1 and that motor smokes like a bastard at older age...
