Hello!

I realize there's a whole lot of talk about idle issues with K-Jet as it is, but I'm not sure I follow the logic of my specific problem.

The symptoms are:

- high idle (over 2k, sometimes with 500rpm blips, sometimes not) with everything connected
- high idle (~1.2-1.5k, no blips) with the ICV connector off
- revs fine, drives fine aside from the high idle

I have the older three-pin ICV. Rubber and hoses are in good condition as far as I can tell. I've gone through electrical testing of wiring to the computer, here are my findings:

- ICV: the voltage between outer pins and the center pin is around 13.21. With ignition on, the ICV acts erratically from what I can tell
- TPS/Potentiometer: I haven't yet tested it with voltage applied, but the resistance between pins doesn't change when the plate is pushed down. Neither is the resistance at the levels prescribed in the service manual when at rest.
- Full throttle sensor: shows erratic readings between 2 and 40ohms when throttle is at full.

My questions are:

1. Should the voltage supplied to the ICV be the same on both outer pins? My understanding was that one pin rotates the ICV one way, the other pin - another way. Does this mean my problem is the controller behind the battery?
2. Since the car drives fine, I assume the potentiometer has to be fine, but my readings say otherwise. Is my testing procedure wrong?
3. Is there further testing I should've done?
