306 idle - thomp1983
hi, my 306 1.9TD 1996 seems to idle fast, unfortunately my tacho doesn't work so i can't tell you the exact speed but ive adjusted the idle speed screw to the lowest setting i c an without the car stalling and it still sounds wrong, ive also adjusted the anti stall speed adjustment screw but this makes no difference and ive also checked the fast idle lever is not sticking on so im out of ideas now, would an air leak contribute to this? any other ideas?

cheers
