Hi,
There are two small plasic vacuum pipes going through the bulkhead between the heater matrix pipes,one of these pipes comes from the bulkhead and is not connected to anything in the engine bay,so basically a vacuum leak! possible causing the fuel trim bank code ive been getting,ive now blanked it off but does any one know what these pipes are ment to be connected too?

Maybe a photo would help.
I don't know the 2.2 engine, but the pipe could be connected to the heater by pass valve or there are various vacuum pipes that are used for the heater controls inside the car.  :-/

thanks mate,you were right,a careful look found that the pipe was disconnected from the heater bypass valve,tight round there!!

...,tight round there!!

You should try it when there are 6 cylinders under there.
