Hi their. am new to this site so any help would be greatly appreciated.
I've got a year 2000 astra van with 1.7dti engine. every now and then, i'll put foot down on throttle and there's no power atall. it just doesn't rev up and stays at the same speed, then as though i've just flicked a switch, it sorts itself out and builds up speed like it supposed to. It seems to happen more when i'm driving it nice like a granny.
Thanks for any suggestions
