I think I need to read through this a few times, or print out the whole thing.
If the engine has been taken out and replaced do you need the diagnostic tool to set it up again?
The idle is going nuts at the moment, as it gets warmer it seems to get worse...
It sounds like one of the small pipe connectors is not attached or has been blocked. There are two attache below the inlet manifold. Check atta re tther and pipes are clear. Sometimes if they are pushed on too bar the tube gets blocked.
One runs from the ECU via the vapour trap to the manifold. The other goes to the air filter housing.
Thanks, I will take a look today
