[pibeech]

please help! my vectra has developed an engine fault! (this car although i love it has been one problem after another) it now judders when driving steaderly feathering the throttle to maintain speed. if i put my foot down its fine, sometimes better sometimes not. please help someone!

is it a 2.5 or 2.6, if its a 2.5 you need to do a paperclip test to give you the fault code, although i'm 99.999999999% sure the problem is the dis pack. Google it mate or go on VVOC.com dis pack is extremely common to fail on the v6 and give exactly the syptoms you described.
