Just a note to say iv'e sorted the fuel consumption problem.

It was the lambda sensor which is situated just before the cat on the exhaust front pipe.

Its job is to sense the emissions coming out the exhaust and report it back to the ECU which adjusts the amount of fuel being burn't by the engine.

The problem that i had mean't it was doing 50p a mile and after fitting the new lambda sensor iv'e noticed a great improvement.
