Supercharged MPI running Emerald ECU.
When I pull off a motorway (constant 70-80 MPH) of say 12-25 miles my car goes really stuttery when I try to gently accelerate and almost stalls at idle. If I give it full throttle it stutters then springs into life. The first time it happened I nursed it for 2-3 miles, then stalled it and upon restarting was absolutely fine. Yesterday I kept the engine running and after about 1-2 miles it started running fine again.
Engine now 6 months old, fuel filter changed, original injectors, original fuel pump. Now has a pressure regulator.
Could it be anything to do with engine bay temperature/spark plugs maybe? The coolant temperature is fine and I also have the bonnet open at the back to let heat out.
Cheers.

CAT maybe? Especially seeing as my CO is too high...

As its a programable ECU it could be any number of things or a combination of things. If its the Emerald, which i think it is, I would be talking to them directly.
