Okay, well, if anyone has been following my ordeal, I have had a rough idle and a high idle. I just got a new boost gauge hooked up and I was barely hitting 6psi. Found a coupler on one of the IC pipes was trashed and sliced, so I replaced it, and also added a valve in place of the stock pills. I have adjusted the valve so I can't go over 10psi when both turbos are boosting. Here is the pattern: 7/8ish-5/6ish-9

Something is screwed. I sometimes can get the car to idle after driving at 850rpm. Usually, when I am driving and get on the off-ramp of the interstate and put it in neutral, rpms drop and stay at about 2k...if i tap the gas...It will go to about 1500...if I sit and turn the headlights on or just wait a little, the lowest it will go is about 1200...WTF. Then, if I wait about 5-10 minutes, I can go start it and it will idle at about 850RPM...but rough...like the motor is vibrating/shaking a decent amount. If I turn the AC blow on to the 1st level, it will idle at about 1000 and be relatively very smooth as far as idle and the shaking seems to be barely there...

I checked voltage on the TPS and it is in spec. Is this the work of the fast idle cam? I can't find any other issues as far as vac leaks. On idle, the car is at 16-18psi of vac. motor has 25k on it.

It sounds to me like you've still got a small vacuum/boost leak somewhere. If you've thoroughly checked all couplers and piping, you might try spraying some contact cleaner around the LIM gasket area.

 

did you also adjusted ur air adjustment screw on the top of the tps? That might help.

 

+1 on the vac leak

 

on top of the TPS? You mean under the elbow? Yes, nothing really changes. Talked with Luis at rotary reliability and he says do a compression test and rule that out, then for on. That is what is next then.

Yep, I would at least rule that out next.
