could be that this is related to your loss of boost issue... but that's just me speculating..

turbo boosting fine must be a blocked or broken cat or somat more expense to pay wot are my options de-cat any good on these will get all lamda readings done next week see wot it is

won't a decat will fail an mot though, you could do a 200 or a 100cpi sportcat as a replacement but if you do that you want it on a 3" downpipe, not a cheap job, prices up to £500. Try that cataclean clean stuff though, a few guys on here swear by it.. I wonder if that new sensor you had fitted is no good, genuine replacements are not cheap to buy so many places used various other aftermarket ones, i tried one in position one (above the cat) and it was so bad

The sensor were a different one forgot name will get some cataclean and ave the o2 sensors checked tomorrow there 2 of em? If it's the cat not bothered about mots as my friend will pass de cat but I bet it plays havoc with the sensors lol anyone ad a 3 inch and sports cat from turbo made up?

[Caveman_nige]
