i have read on many of the forum pages, about an idle valve, which can be cleaned to stop erratic tick over speeds(which prob does'nt work in all cases), anyway i would like to know where this thingy is because i have erratic tick over on gas, but petrol seems ok so maybe cleaning this valve may help.
please tell me where to locate this thing, by the way i have a mk2 gti 16v if that helps
