went in my mums polo for the first time in ages yesterday and it has developed this weird revving issue.... not sure on the year but it is the first GTi shape when it is idiling the revs stay above 950 but constantly rise to about 1400 then drop down again, then rise againa nd it just does this continually.. think this is called huntng but maybe wrong! lol anyway, does it have vac hoses that I could easily change, or some sort of isv that could be causing it? I know most people on here hope to one day own a 1.0 Polo or maybe already are lucky enough to so any help appreciated!!!
