SiR_RB Posted November 4, 2017 Share Posted November 4, 2017 (edited) Hey fellas i got an issue that just arised last week and it's driving me crazy ! car will cold start and idle fine, hot idle is fine but when I'm driving if I down shift and the rpm is over 2000rpm and then pop in neutral it will stay idling at 2000rpm sometimes it might fall back down to 1000rpm after 5seconds or so but most of the time it will stay there until I pump the throttle then it will settle to 1000 if the car is idling and I pump the throttle again it will idle at 2000rpm until I give the throttle a quick jab the it will settle im running a hypertune plenum and 90mm throttle body, gave the throttle body a clean afew days ago and did a tps reset still no change also did a pressure test and seemed good I noticed driveability issues around the 2000rpm like it surges too i spoke to hypertune and they said to send them the throttle body to test (incase shaft seals are leaking, it's only 2 years old) and to rebuild if necessary if anyone has any other ideas I can try that would be great thanks Edited November 4, 2017 by SiR_RB Link to comment https://www.sau.com.au/forums/topic/472588-r32-gtr-occasional-2000rpm-idle-help/ Share on other sites More sharing options...

GTSBoy Posted November 5, 2017 Share Posted November 5, 2017 Clean the AAC valve. Take it off, dismantle it, dose it with carby cleaner and a toothbrush/pipe cleaner.

Sub Boy32 Posted November 17, 2017 Share Posted November 17, 2017 (edited) What are your plastic throttle spring retainers like? I had a similar issue and it turned out being the plastic retainers had perished and the springs were binding edit: scratch that I've just read you are running a single throttle.
