Air regulator/IACV trouble

[alundra]

Hi guys,

I tried to fix my idle. In cold situation, the idle doesn't go over 1000rpms according the FSM, it must go to 1500rpms range than reduce slowly to 750rpms+/-50. Mine oscilates between 650/800,

I tried to find a ECU code error, nothing. I tried to find a leak, nothing too. So i tested different sensors:MAF, water temp, detonation sensor, spark plugs+wires, timing and distributor rotor and stator, no success.

So i tested the IACV/air regulator thing. According the FSM the device itself must have continuity between the 2 pins, not mine.
I bought a second hand IACV, it doesn't have the continuity, according the seller it came from a car that runned good.

So i'd like to know if someone has a good cold start, how it shows on your tachymeter and if he can test the continuity between the 2 pins on it.

I'll appreciate that
