matthew_harwood 0 Posted March 5, 2005 Hi guys really need some help with this problem thought I'd got rid of it but its come back :(!!! Ok here are the symptoms, will not idle when the problem happens at all, if you hold the pedal at 1000 it goes from 1000 to 1500 and continues to do this until you move away. At low speed when you accelerate there is a pronounced hesitation. But as you get to the higher speeds it seems fine. Thanks in advance Matt Quote Share this post Link to post Share on other sites

Supercharged 2 Posted March 5, 2005 You tried cleaning the ISV? Quote Share this post Link to post Share on other sites
matthew_harwood 0 Posted March 5, 2005 Hi silly question but where is the isv and how would i go about cleaning it regards matt Quote Share this post Link to post Share on other sites
Riley 0 Posted March 5, 2005 the isv is a cylindrical valve,i think its on the right hand side of the engine in the valver? it has an electrical connector going to one end and a pipe on the other. best way to clean it is to soak it in petrol. neil. :D Quote Share this post Link to post Share on other sites
matthew_harwood 0 Posted March 9, 2005 Hi all still have this same problem, have cleaned the isv valve didnt help at all, the car will cut out every time when you dip the clutch. it hunts when below 2000revs but will be stable at about 2000 with out hunting. anybody got ant advice thanks mat Quote Share this post Link to post Share on other sites
potatonet 0 Posted March 9, 2005 new ISV and make sure its plugged into the back of the throttle body like on the G60's. if it doesnt plug in there try O2 sensor, and perhaps dizzy. Quote Share this post Link to post Share on other sites
2cc 0 Posted March 10, 2005 Poss air leak on a vacuum hose. Had a similar prob on mine years back (cutting out slowing for roundabouts/junctions - very unsettling at times) tho it wasn't as pronounced as yours seems to be. As you say, not so noticeable at higher revs. Can be a bugger to track it down tho. Luck Quote Share this post Link to post Share on other sites
matthew_harwood 0 Posted March 10, 2005 Hi all just an update, today I fixed the problem it seems that the valve at the back of the metering head was clogged with oil and wasn’t allowing air to pass. Does anybody know what it’s called? Regards all matt Quote Share this post Link to post Share on other sites
