all of this is good and will improve your car but probably wont solve your problem, it might even be the coil packs at fault?

i know very little about coilpacks - where are they and what are they for - Also a very long time ago on this forum i read that Motorworld in Oxford do free coilpack changes because they had recalled in the mk4 for their crap coilpacks...? Not 100% if it was a recall but definitely remember them doing it for nowt.

The coil packs are the same as HTleads normaly found on older cars, its the lead that conects onto your spark plug, so if one has failed it will cause the car to only run on 3 cylinders.

best to get a digonistics to see if these are at fault.

How expensive is it to replace and can i do it myself?
Your right if the car is running on 3 cylinders then thats bad.. my only objection to that diagnosis is that the car runs fine after about 5-10 minutes and its only when started i have this judder problem, but then again it could be an existing problem because the idle at start is higher than normal then it flats out but is not steady - will have to see what codes come up at my mates garage.  :smiley: :smiley: :smiley:
