Ok--in open loop the ecm does not use the INT or BL for fueling --its all off of preset fuel mapping.... So if its surging when it goes into closed loop its due to the fuel mixture. As for the IAC--you want it at 15-20 counts. You achieve this by adjusting the idle screw or for lack of better terms--close the throttle plate to increase IAC counts/open the throttle to decrease IAC counts What style of TPs do you have? Does it have the round style terminals or small flat(when you remove the tps connector). As for TPS you will just want to experiment--never going over .68 volts at idle.
