My son had an air flow meter fault and yes the chaps right it didn't show up on the diagnos. Would be ok then sudden loss of power and you can't drive through it, the more throttle you give to overcome the loss the worse it was. It started off as an occasional slight loss for a second or two and went to total menace.
We had it on several diagnos and everybody had a different theory, if you can get a friend to let you borrow his air flow, go for it, if it does it constant then, use his as spares until you get it. That's what I had to do, the parts are just too expensive for trial and error. At one point I was going to hire one and take the bits off it, I was so pissed off.
