Thanks guys!

I have booked in to see Flea next Thursday (4th July).

Hopefully it's something silly and cheap. I'll be both happy and p'ed off at the same time if it is!!

I haven't enjoyed my Coupe since last September, so I can't wait to get it sorted.

I've been watching, but it's been a few years since I had to fettle a 20vt so I don't have any immediate suggestions. If anything comes up, of course... My best guess, given your list of changed parts, is an air leak post the MAF, but a guess is all it is.

Thanks Neil,
An unmetered air leak was my thoughts also, but I couldn't find any using gas or carb cleaner.
I aksed my local garage to check for vacuum leaks and they couldn't find any either confused They measured vacuum as 17 in Hg.

Your in safe hands with Mr Flea!

And should he breath on your coupe and tune it - you won't be disappointed!

Check the earth from battery to chassis, check earth under rear lights nearside and also check the plate under inlet plenum just above chod .
Check all nuts are tight .
Might just be something simple like this .
Fingers crossed

So...
I visited Mr Flea yesterday and he diagnosed the problem as rubbish, aftermarket, non-genuine, far Eastern fuel injectors!
My mistake for buying 'good value' components! I would have saved hundreds of pounds in parts (as I was going through a process of elimination) if I had just bought new genuine or even used Bosch injectors.
Fortunatley for him, the E-bay seller has agreed to a full refund (after a small messaging bun fight). These injectors were marked with the Bosch registered trademark and so were legally counterfeit!
Lesson learned; move on and enjoy the ride I'm now getting thanks to FC Performance!

Hmm, interesting. I bought a set of Bosch injectors a while ago, and they should have a special security code and "silver" sticker or hologram plus "data matrix" code (like a QR code) on a strip of paper sealing the box that directs you to www.protect.bosch.com where you can check if you have a genuine product.
