after driving for a whole two days in my mig i feel it holds back a little under acceleration sort of spurts it'S way up to full gas but only slightly but i notice these things so tomorrow will be a day of cleaning the butterlies e.tc but i've been at the guides and don't really see one for breathers  i take it there are breathers that need cleaning on the 2.2 if inyone can give me a linky it would be great, many thanks, rich.
