paceo 22 Posted March 18, 2012 Report Share Posted March 18, 2012 i promise this will be my last post about the idle, when cold its ok when warm it idles anywhere between 500-650rpm hunting. ive now run out of ideas - new lambda sensor, new leads, new dizzy, tried several idle control valves, tried another throttle body, tried another inlet manifold, sprayed engine to too see if theres any air leaks, replaced all vaccum hoses at back where idle valve is, new temperature senders, cleaned the MAF and tonyvrt has had it on VAG COM and there are no fault codes. :-( Link to post Share on other sites
Biggazvr6 0 Posted March 18, 2012 Report Share Posted March 18, 2012 Have u checked fuel pressure to see if reg is failing? If it's not ignition side n electrical the only one left is fuel side. Also when did it last have fuel filter change? Is pump noisy etc etc Link to post Share on other sites

Also when did it last have fuel filter change? Is pump noisy etc etcyou mean the 4 bar regulator on the fuel rail? fuel filter change was about 1000 miles ago. fuel pump isnt noisy.it drives fine fella, no missfiring etc but this just bugs me!

legvw 0 Posted March 18, 2012 Report Share Posted March 18, 2012 There is an adjustment screw on the throttle body, adjust that screw when warm to get the correct idle. It may idle higher when cold, but what vr doesn't? Link to post Share on other sites

legvw 0 Posted March 19, 2012 Report Share Posted March 19, 2012 I haven't got a t/b to hand but it's around the by the throttle body. You might have to remove the rear engine cover to see/adjust the screw. Link to post Share on other sites
