Yeah should be backlit, I bet one of the bulbs has blown in the clocks.

It is supposed to read --- below 50. If it is swinging all over check the wiring, the green/black one at the fliter mount. It could be shorting to earth??

When you have an airleak, the MPG reading climbs up to 99.9, as it monitors vacuum to give it's estimate, when there is no vacuum it assumes you are using no petrol(if only!)

It could be a bad earth, the one for the clocks is a brown and white on the back right hand cam cover nut. IIRC.

The vacuum hose has a habit of falling off the back of the MFA.
