Thats very poor mileage indeed, and suggests more than a choked air filter or binding brakes for example - although I hope these things have been checked!
If the exhaust tail pipe is sooty and maybe producing black smoke, the cold start device may be stuck on....its similar in operation to the choke of old.

dark night, high cliff, report it stolen.

Sorry that was a bit flippant..

Have you checked and cleaned the mass air flow sensor?
also main air filter, if this is choked excessive fuel compsumption will follow.

I don't think you'll need to remove the lambda sensor - normally that would put the engine management light on if there was a problem.
Remove the spark plugs, and see how sooty they are.

The lambda sensor
measures the free oxygen in the exhaust gas stream.
