Petrol Overconsumption

Hi, I think i have a bit of a problem with my car
It's an E36 320i automatic
Lately it has been burning about three litres of petrol for a 2 mile journey.
I know i have to replace the Idle Valve, but don't think that will cause this anyway.
If there is a leak where could it be.

P.S. I know it's not the tank.

Thanks

Well, the idel valve problem causes fuel injection to go up and down all the time. I especially notice that when i'm going at constant speed on the motorway. I can also see the MPG indocatos going up and down. You think it's that?
By the way the cardboard thing i've tried alredy and there's nothing.
