Jez 0 Posted December 6, 2005 Got this problem yesterday, seems my engine is idling at roughly 1200rpm even when warm. Not fluctuating though so I don't think its the ISV that's knackered, plus theres no other noticable diffrences to normal running. Cold start valve jammed open maybe? Anyone else had this problem?

Supercharged 2 Posted December 6, 2005 On a VR or 16V??? (don't think the VR has a cold start valve...) Quote Share this post Link to post Share on other sites

g60griff 0 Posted December 7, 2005 ive got this problem with my g60. it doesnt do it all the time tho Quote Share this post Link to post Share on other sites
shawshankkid 1 Posted December 7, 2005 My G60 does too. Not all the time though. Quote Share this post Link to post Share on other sites
colinstubbs 0 Posted December 7, 2005 my 16v has done this since i put a webber redline porsche 924 throttle body on it. it's intermittent and partly due (i think!) to a weaker spring and having to run the throttle cable to operate in an anti-clockwise direction so the run is slightly different. Also it stuck at 2500rpm on tuesday, so maybe after 160k i could treat my motor to a new cable, a quick blip sorts it but i'm getting pissed off with having to do it as i pull up at traffic lights and junctions cos all the nova and corsa boys start getting twitchy :oops: Don't know how much a new cable is?

chaz g60 0 Posted December 7, 2005 mines was idleing high, i found a vacum hose was off. check all your hoses e.t.c.? Quote Share this post Link to post Share on other sites
Jez 0 Posted December 7, 2005 Yeah, there is a hissing noise coming from around the throttle body to honest. haven't had time to get the plastic cover out the way to see if there's an air leak anywhere yet, will have a look tommorow though... Quote Share this post Link to post Share on other sites
chaz g60 0 Posted December 7, 2005 Yeah mine was hissing and it was the little t section coming off the tb, the pipe to the left was off and it was sucking air in. I put the pipe back on and the revs went back to 750... sorted Quote Share this post Link to post Share on other sites
Jez 0 Posted December 8, 2005 I think now it is the ISV thats stuck open as the hissing noise is coming from the box like filter that sits behind it indicating air is flowing through it (its not leaking either, was brand new in august). Quote Share this post Link to post Share on other sites
Trig 0 Posted December 8, 2005 The plastic box thing sitting behind it is the silencer and it is normal for it to hiss. Quote Share this post Link to post Share on other sites
Jez 0 Posted December 8, 2005 Anyone know how hideously expensive a new one is? The ISV that is... Quote Share this post Link to post Share on other sites
Guest Posted December 8, 2005 Anyone know how hideously expensive a new one is? The ISV that is... Have you tried just taking it off and blasting some brake cleaner through it? Sometimes helps Quote Share this post Link to post Share on other sites
Jez 0 Posted December 8, 2005 Yeah was gonna try that first but just curious as to how much a new one might cost. Quote Share this post Link to post Share on other sites
Guest Posted December 8, 2005 Yeah was gonna try that first but just curious as to how much a new one might cost. Not too sure. I got quoted £25+ vat for a second hand item for my old golf :shock: Didn't bother in the end, just cleaned it :) Quote Share this post Link to post Share on other sites
