89/90 sidekick idle speeds 800/920rpm

[spiritofr]

Fixkick, I'm getting 0Vdc on the ISC pins and I've backprobed both sides of the connector while connected, I even pierced the wires with the needle probes to make sure I was touching metal, and I tried two different DMM's at 20Vdc. What do you think is going on? My idle seems pretty good and stable, always 750-850, and 900-1000 with accessories on. Earlier this week I turned the TB screw until 800rpm and calibrated the TPS with 0.086" gap (5 gauges stacked) turned to 250-350ohms, the throttle feels pretty good. I recently cleaned the EGR and installed a new fuel pump so the car starts great on first crank when cold, RPM goes to 1800-2000 for a few seconds then quickly down to 1500-1600 and then very slowly down to 800 so I assume the dashpot, IAC, and temperature sensor are working.

Thanks for your help!
