Thanks for the interest mate

I have tried a few things
Checked for leaks on inlet and exhaust side, but nothing showed up.

Map sensor hasn't arrived yet, but tbh I don't hold much hope, as the reading on the IAW seems to rule it out.


but one thing I have completely missed to is that I have to drive without the ISCV connected, because it plays up and makes a strange sound when connected. I put it down to that because it was very rich it behaved strange, but now I am unsure if it could be related.

I haven't checked injectors or filter
How could filter cause this?
the point of the injector I can understand - I guess you refer to if one of them was leaking?

It is also extremely rich on cold startup for a couple of minutes, coughs and misses until it get a little heat into it, if I leave it to idle. But if I drive off right away it drives ok from cold.

now that I put that in writing, it makes me think if you could have a point that it could be injector related....a leaking one perhaps??
I have also considered if it is the chip that needs adjusting, or if my ECU reset method is wrong.

damn car....

I should mention that on boost its very good

thanks for reading
