Idle speed.

[Gozza]

Can someone tell me how to set the idle on my 1988 golf gti mark 2 16v. I know where the idle control is on the inlet, but I remember from my last golf you have to disconnect summink and plug summink up.

Can anyone remind me, pics of the bits I need to fiddle with would be superrrrrrrrrrrrrrr

Thx

aye disconnect the red wire on the coil to disable the ISV (if your ISV is working the revs will plummet) & disconnect the breather hose on the air box

[Gozza]

breather hose, is that the one that branches off to the right and goes along with the ht leads

And the wire I need to disconnect is that at the top right if the engine bay ?

[Gambit]

no. it comes out of the actual top of the airbox and runs into the front of the block.

the other pipe is the vacumm used by the ISV

have a look here:-

its the thick black pipe u see below the injectors on top of the airbox, and running behind the alternator

also this is a good read for setting up a 16v:-
