CLIO PH1 172
so angry i thought i had this problem solved !! 






my 172s idal was all over the place and i tried loads of methods to fix the problem and after fitting a new ICV the problem finally went, and ever since the car has idaled perfect every time.
BUT
today i came to some lights, stopped and the revs started to pick up again. i thought agggghhh here we go again!!!! so i drove the car home and i was right the dodgy idal is back!!!
so i popped the bonnet with the engine still running and the revs all over the place around the 3/4k range, and when i squeezed/blocked the breather pipe (the one that is attached to the ICV and the induction pipe) it idaled perfect again ? ? ? ?
why is this? im now thinking can i just block it off and thats it? ? ? ? or does it need to breath and have air getting in there ?
thanks
