hey! now i know its not a ford, but I know these things (MAF) are notorious for dieing on escorts. usually from oil.
They say the oil on these oiled K&Ns is no good for em!

(the MAF's that is)
seen massive impact on power when they die, and a big jump in power when they are replaced with a known good item
Perhaps simply 'un-plugging' the MAF on a turbo car is no good for fault finding, as it's dealing with a lot of air.
Have u tried another MAF. ? new or known good one?
infact! is your MAF capable of measuring the correct air? Maybe it don't like your lower temps/ denser air from your charge cooler. Or perhaps its just a dud?
