Anything and everything to do with maintenance, modifications and electrical is in here for the Mk2.
From first start of the day what is your idle speed....
And do you get a clean rev on a short sharp throttle blip?
Mine starts at 1500 and climbs to 2000. Im sure its not right along with the very slight dip when I blip the throttle as if there is a momentary loss of power, this only happens when the cold idle is high making me think its related

Idle will be anywhere between 1500rpm and 2000rpm when cold so what your getting is normal
To add mines an na, a little reassuring to hear others similar idle. I worked on a rev2 today which sat solid at 1400
If i block my iscv hose it stalls instantl. I've also swapped complete throttle bodies with identical idle speeds just seems to hammer the clutch?
I'm having the complete opposite, my rev3 turbo will just start, then idle at 750/800 from cold. Any ideas what I should be looking for? sensor to replace maybe?
Most likely it'll be the ISCV (idle stability control valve) gunked up and not opening properly (or at all) on cold start. It's a part of the throttle body so once you've taken that off, it should be quite obvious
Have a read through this thread, JeffD done a great write up on what to do : http://www.imoc.co.uk/forums/viewtopic. ... light=iscv
Ok the only thing that's causing the high idle is the iscv, blocking the pipe to it stops the engine. It also relates to the dip when revved as if the idle speed is forced lower it revs fine...
So what initiates the raised idle....coolant temp, water temp in iscv, possibly air temp? Ive replaced iscv, coolant temp sensor and air temp sensor
