Hi Mate I have had the same problem recently with my 8v GTi. Take a look at my link "Name that part" in the Mark 3 section. I removed the plug connector from the carbon cannister and have been driving the car for the last few days with it unplugged and it's been great, faster and no cutting out and the revs drop to a normal level when I dip the clutch. There is a pic in my link and this may help or may not. I have been advised in the link to clean the air intake pipes and the throttle body which I will try this weekend. Hope this helps Cheers Deano
