Gti6 idle issue

[NottsPug]

I'd be stripling the the icv, giving a really thorough clean and grease up, clean out the pipe that comes off the icv, also cleaning the butterfly valve making sure that is getting stuck slightly. Also check throttle cable is connected right.
Also check you actually plugged the icv back in and done the bolts up nice and tight. Also check the o ring seal it has and make sure it's all together correct

Thanks I'll strip it off again tomorrow then. I haven't touched the throttle it is brand new cable. When I took it off the first time it was fine but didn't resolve my stalling issue. It has only been since I took it off again and pulled the black sleeve back to crease the shaft that this new problem has appeared. Thinking maybe I have damaged it or something
