Ive tested the solenoids that Karack suggested, and found that they dont pass when I use a 9v, but they pass when I use a 12v. Does anyone know what voltage the ECU supplies to the solenoids in the rack? I would assume 12v, since it is a 12v circuit. Would it be okay to use them?

I put the battery in and tested the connectors with volt meter. The switching solenoid gets 12v across the connector. But the relief 1 solenoid is only showing .2v across the connector. When I ground the positive side it shows a full 12v. So i'm guessing something isn't right in the harness. Unless it is supposed to do this?

I checked the FSM, the voltages are correct. The relief solenoid goes to 12v after warm up.

Im gonna try and use some rtv on the IAC and ACV, and see if it makes a difference when I put it back together. Then ill try covering the ports, and if it shows I have a leak ill try it on the UIM. I dont think I need it there, the gasket is brand new. Then if that doesnt work I guess it has to be my LIM.

Well the rtv on the ACV and ISC didnt work. I blocked of the intake plenum and the car died. With the plenum off I stuffed a rag in the throttle body and the idle went down to about 900. I sprayed carb cleaner and found my throttle body gasket had a leak. I've got rtv on it, now im waiting for it to set so I can torque it down.

The rtv on the throttle body has helped idle is about 1200rpm now. I guess tomorrow Ill put it on the UIM as much as I don't want to. Im really starting to think its my LIM gasket though, but I would hate to do all that work and find it still has the leak.

I did try the plugging off the brake booster line as well. Still didnt change anything. Im guessing that it gets worse as it warms up. When I start it its at about 1200 then it very slowly climbs to about 1300 as it heats up.

I also have the same issue. My idle is at 1200 RPM and will rise to 1300 RPM then begin hunting.

I adjusted my TPS to spec, and fooled around with the Idle Air Adjustment screw underneath the TB.

I'm in the process of cleaning my IAC valve and changing the LIM gasket since I already bought them. What I did find though, was that the IAC valve gasket was paper, rock hard, and stuck to the UIM. I had to pry it off and scrape the paper with a razor blade. I'll report back if anything changes.

I pulled the LIM and put on a different gasket that I had. No change in idle though. Its time to sell this thing me thinks.
