Think i saw a post about a loose heat shield causing rattle issues...
just a thought mate !!
cheers for the replies guys - i stuck it in another garage to the one i normally use to get a different view as its not even idleing now , as soon as you stop and take your foot of the revs it just dies - they rang me in work with the news that it was down on two cylinders and they reckon its the headgasket - so i said how much and he quoted me £800 - thats right - i'll just say that again in case you think i hit the wrong key £800 ! - i'm off to the headgasket section on here for ideas - i mean how hard can it be lol
