The motor is an Rb25de from an R34. I noticed my tps voltage was .20 closed. I adjusted it to oem specs at 4.5 or so and that's when I started getting the high adle around 1300-1500. If I unplug the aac the idle goes back to normal. If I set any values on the aac in consult the idle goes back to normal. I thought I may have a bad tps and installed a new unit but the same thing. The aac adjustment screw is all the way down (and broken so I cant back it out again). I've cleaned it out a while back but never had an issue until now. Not sure why my idle is screwed now because I touched the tps..

Before you say this has been covered, I have exhausted over an hour today trying to navigate this site and going through greddy install diy posts. I don't need help on the full install I am fine with that I am confused on one aspect. Every greddy plenum I see installed in photos online do not show the aac valve connected to the pipe preceding the throttle body. When I look at the diy or other forum topics none of the images load, whether that's because the post is from over 10 years ago I'm not sure. If anyone can confirm what they did with their aac valve when installing a greddy plenum I'd greatly appreciate it. My tuner has heavily recommended I keep this for a number of reasons, suffice to say he is one of the best in qld. Car details - Rb25det - linkg4x - greddy plenum - high mount turbo gt35 - 1000cc injectors - forged pistons rods etc Situation - Street use and drift car at the track, not a daily car but would prefer to keep a/c and cold start. If anyone has any reccomendations, id appreciate it as i said. It doesnt make sense to me putting this into the pipe preceding the throttle body on top as its ugly and i csnt see that on any other setup, unless everyone runs it underneath or not at all im very confused... 😁
