Hi Mozz,

You might find this of some use for reference;

Cleaning a Mass Air Flow Sensor | eHow.com

I use intake cleaner, as suggested, otherwise known as carb cleaner or brake cleaner. Its basically a strong decreaser solvent in an aerosol can.
Its highly flammable so would recommend using it only with engine cold or atleast cool, and if the engine is running keep the stuff well away from sources of ignition (like the ignition coil terminals).
Better still is the unplug the MAF and remove it out of the engine bay for cleaning.
Somtimes works, sometimes doesn't.

Its one part thats always worth having a spare of in the garage

Brake cleaner is basically alcohol and will evaporate with no residue. you must use this in brake system work.
Carb cleaner (some contain Acetone) has some other stuff in that will leave an (oily) residue. For many thing they can be used interchangable but for some things you must use the specified solvent in order to break the crud you want to clean.
Anyone who uses brake parts cleaner to clean throttle valves and around the intake, be warned - what comes out of the tail pipe when started is very toxic....

dont do that mozz, if your unsure of it being the maf and you can get over this way i would let you try mine if it helps you..

cheers john i will try and get some proper spray on monday and give it a whirl or failing that will see if joe at emmotts has got a newish one in , its annoying really as i only changed the air filter box cos mine was broke and the maf unit came with it and he kept hold of mine in exchange ,,,never mind these things are sent to test us , cheers matey ...mozz
