modified recircs fixed my issue... then again, i don't have a tune yet. I would go over the little stuff like making sure that the TPS is set right. and check the FSM to ohm out the connections on the IACV assembly. [ http://z32.wikispaces.com/Idle+Control ]
My idle is dialed it at about 900-950 and stable EXCEPT during the initial warmup when it decides to hunt. Haven't troubleshot that yet.
