Amongst other things iv got high CO and high lambda at natural and fast idle

CO usually means the cat

bollocks

could if give those results if the center section was nackered. ie. a hole in it? cos mine had rotted through

^^^ jack car up and give the cat a knock with your hand if you hear rattle then its fucked. unscrew lambda sensor see if ceramic is broke/missing/cracked. 17mm spanner on manifold.

All else do what i did and tell them to run it thru hot just race hell outa it and tell them to test soon as get there it past mine and mine was well over on all too.

thats the way to do it.
although the MOT centre i use, brilliant good mates with the owner but neverless... dont have the equipment to test emissions but fully licensed to give out MOTs. dont know how that works, but if your ever in the SW / plymouth area hes the guy you want.

also will pass you for anything aslong as you dont have cut springs

jsut got to buy him a box of jellie babies and cup cakes!
who doesnt, if your nice and give them something on the back hand these days!
