Anyone ever had a clogged CAT? My cars giving me some problems, serious lack of power on acceleration and particularly when on boost, spluttery and jerky at times but never stalled yet, getting crap MPG(15-19 at a steady 70mph). No vacuum leaks(trust me I've checked!) all new silicon vac pipes, new PCV/reconed turbo 6k ago, lambda has about 25K on it, new fuel pump/MAF/plugs/dizzy + arm/Leads/intercooler/FPR/TPS! No Lambda light as yet but something's wrong. Im convinced its the CAT as the exhaust smells wrong after a long run, weird thing to say I know but................ I know I need to get the back pressure tested at the lambda/before the CAT but cant do anything for a while as im stuck at work so thought id ask for any advice....
