Hey folks

I got a car, a ford mk4 1.6 cl (1988), which was later rebuilt with a 102 hp xr3i efi engine. (1990)

Yesterday i went out to throw a green filter on it, i blinded the hoose going to the irv (no place on the new filter for it) and it still goes like nothing ever happend?

Its keeps 1200 rpm when cold, but when in running temperature it swiches between 1500 to 2000. mostly 2000.

How come my irv didnt make a different at all? Im getting sick of hearing it idling so high all the time, rather embarrasing.

Any ideas aout whats broken?
