MGF running rough when cold

Hi all

I'm now the proud owner of a MGF vvc and I loooove it. However, I have a small issue. For some reason it's not running sweet. When it's cold you can really notice it's missing and the warmer it gets the nice it runs. I don't seem to have lost any power and I've changed a few things. New spark plugs leads and coils
Fuel filter new oil and coolant
I've noticed that the exhausts seem to puff along and I've checked the new plugs and the 2 closest to the vvc unit seem really black compared to the other 2. Also if you unplug the cylinder second closest to the vvc it doesn't really make any difference until you Rev it. This is really confusing. Any help would be appreciated oh and I forgot to mention I have no codes and no EML on.

Where are the bottom timing marks when you see this?
