Hi everyone, thanks for your replies. Sorry i havent got alot of time at the moment so thisll have to be real quick til later

Firstly thanks for the welcomes

Its absolutely not transmission related.

There were no codes a week ago when it was checked out and had transmission serviced.

Fuel used is 98 RON BP premium unleaded.

This time of year in Australia, itll be well over 40°c after 2 or 3 minutes of running. Very warm weather here lately

Idles perfectly fine right from cold. Foot all the way down or just part way down, issue is the same, obviously the pickup is alot more savage when it hits if youre at WOT.

Oil light tells me to add two litres of oil, the cluster in the 230 is different according to the manual. But thats ok, its sorted, got new part coming to swap out.

Pagz, you mension butterflies inside the manifold, what do they do and where are they?

Is there a way to check the DTCs without a computer or is there something i can get for a laptop?

Thanks again everyone
