ok...before i start spending money on what the garge have said, can i just get some quick advice??

Around Apil last year I changed the Second Injector and injector line after the connecting bit on the banjo broke.

i got the injector of ebay...cheap with the red pipe.
Could the injector be faulty affecting Cylinder 3?? and causing excessive fuel consumption??

or would this problem be the metering head?
