Pull your coil pack out and see if your plug wells are full of oil

MAF reading zero is surely key? 

Have you tried unplugging it?

Yes maf 0.00 can't be right with 90% throttle load.

I have a seperate thread running about my MAF here:

Changed the coil pack for one I got as a spare from breakers a while back and all ok again now - nice round trip Bournemouth to Portsmouth and back so pretty sure its fixed :-)

Thanks for all the tips.
