hi i have looked through up to about number 24 of all Threads hoping to see if i could get the answers with out having to ask, but no good. So l here we go. its a 4.6 Dec 1999 petrol 140K miles she starts no prob but when i try to pull away she splutters and loses revs i take my foot of and wait when she warms she is no bother until i am cruising about 60 mph and put my foot down to over take and then very little there.
