i have a s2 rs and i have a running issue it will start in the morning after a couple mins but there is no tick over and you have to rev hard to keep it going and as soon as you take your foot off it stalls and wont start again unless you leave it for a least 24 hrs does any body have any idea what this could be cheeRS for any help.

 

I had a simular problem which tuned out to be something to do with the cold start valve so i unplugged it and it was fine after that, Or it may just want a set-up? I know MFI can be a pain.

 

idle valve screw on the underside of the throttle body??just a
thought

 

run some injector cleaner in your petrol to see if that helps. cold starting and poor idling can be caused by many factors, I had a bit of a valve missing which caused this problem.

Try starting the car with the metering head flap pressed down slightly, it might need the metering head setup!
