The car has a rattly sound coming from around and below the throttle body assembly, not sure if this is related or not.

Have so far changed the cat, lambda sensor (HEGO), MAF, Plugs and leads and a new battery.

There is gasses coming from the exhaust, although it does seem strangled as the exhaust note has changed, despite air passing through the backbox.

Going to get underneath and change the fuel filter and check the fuel lines and maybe try another pump. It is definately getting petrol, because its using it quick enough - but no performance.

Beginning to think it may be time for the escort to go, had about enough of it now.....
