Mk2 Golf GTi Issues.
Discussion
Evening,
As this is the resident PH VW section I was hoping there may be some mechancially minded Mk2 owners here.
I said I would have a look at a friends Golf that he has been having issues with. He's not particulary car savvy but I believe I have worked out most of the issues. The only outstanding one concerns cold idle, the car likes to hunt quite a bit. Apparantly this goes away when warm.
I don't know much about Golf's to be honest but is this a ISCV issue, or a MAF problem? If its common some pointers would be quite useful. The Golf is the 8v version with the Digifant system.
(Incidently, can anyone give me the name for this part so I can get it ordered? I believe it's part of the vacuum assembly for the brake master cylinder. Well was, its had bits snapped off it!)
Thanks for bearing with me, most appreciated.

Two common culprits are the ISV and temp senders (3 of them) - the temp senders can all/each cause poop idling and are on the nearside of the cylinder head down and left from the dizzy.
The idle stabilisation valve gets filthy, to clean it pop both pipes off, put your thumb over the lower hose hole and squirt a bit of meths in there. Get a mate to turn the ignition on so the ISV runs, repeat a couple of times if neccesary until the meths comes out clean. Should buzz quite agressively when the ignition is on if it's working correctly.
