Default Power loss at 4000 rpm GTV 2.0L

I took my GTV out for a blast the other day and I experienced
distinctive hesitation at around 4000 rpm. Every seemed fine up until
then, but as soon as take her over 4000 she holds back, (similar to
the rev limiter) then struggles her way on up to 5000, 6000.
Then yesterday I started her up on the driveway she started to
splutter when I revved to 2500/3000 rpm but then cleared her throat
and and was fine until 4000 when the power loss was evident again.
So yesterday afternoon I took a trip over to Alfanet in Bristol, to
have a diagnostic test, which showed no faults. But the chap there
said that the air flow meter may be faulty so he swapped one with
another GTV that he had, and asked me to try it over the weekend.
On the way back over the Severn Bridge I put it to the test, and it
appears to have made no difference.
Any suggestion gratefully received.

The air flow meter thing seems to come up over and over again so it
may be relevant. However, you should check some of the easy things
too. It could be a fuel flow problem, check that the fuel filter is
clear of muck and water. Did you just fill up before going out ? You
may have some contaminated petrol. Make sure that air is getting into
the fuel tank (I'm not sure if there is a vent of some sort on the
petrol cap. Check that the exhaust is not partially blocked by a
collapsed baffle. Give all of the boxes a thump and see if anything
rattles. Make sure the air filter is not blocked or collapsed.

I'm sure that there will be other possibilities too.

Regards
