Have you cleaned the map sensor tiny hole and clean all the holes in the TB? Verify all vacuum lines are connected properly
replaced MAP, TPS(0.3-4.5v), IACV
cleaned throttle body inside and out
valve adjustment
new plugs wit correct gap and torque
no vacuum leak (blocked 2 ports in the TB)
idle relearn each time
next step would be injector tested and cleaned. Im almost to the point of giving up. This f@#king car is breaking my wallet. Sad to know the dream car ive always wanted and enjoyed idles like shit

well all i did for that hole was blow air in there. didnt use a q tip or carb cleaner or anything. Any suggestion on what to use to clean it?

MAJOR UPDATE! I finaly fixed the stall issue! I took it to the shop and got the injectors swapped with a clean/tested one and didnt do much of a difference. Reconnected the PCV to the intake manifold and BINGO. Everytime the PCV is not connected the car will stall. I had the PCV valve capped and also the manifold side capped due to big puff of smoke during track days (Recommended by rob robinette).I had a catch can attached to the breather side of the valve cover before but now i run the PCV to the catchcan, and back to the intake manifold while the breather side stay open atmosphere. When the PCV is connected, the breather side is actualy in vacuum, but sometimes oil will still come out very slightly so i will now run dual catch can for both breather and pcv side.
Here are the update videos of my car with a fixed idle! I hope this helps for those who experience the same issue!

UPDATE! I know this is an ancient thread! Finaly got to the bottom of this. Ive had at least 2 more CEL after this thread ended and they were all TPS codes. Im running the omnipower so i was like wtf. The code kept saying low circuit so i bumped it up to .4v the first time thinkin it would make the idle a lil higher. Engine light came on again yesterday and same thing TPS low circuit. Did some more research and i finally fixed it!! I had to set the volage .28v at closed throttle then booom its all good now. I can finally use my damn AC without the car trying to die! Wrong calibration all along
