I have Gti-r and recently it started idling very high at 1700-1900 and rarely drops at all...the idle screw is all the way down and i tried throttle body cleaner and still no help...there seems to be no vacuum leaks as it reads 20hg on my boost guage and currently im thinking its the increase in temp but not to sure as im still running the top mount...any help would be great as i cant set timing and its pretty annoying and loud when idling that high.
