So.... (sorry to do this) now that you're an expert
maybe you can help me with something my car has done ever since I've had it but I never bothered to sort out...!
When cold, it idles very low, almost as if it's going to stall, and when you start it you need gas to get it going. Then if you let off too quickly it will stall. It's fine when warm (though idle is not 100% smooth), and it's adjusted fine (as done on computerised emmisions test). Other 4-cyl MBs seem to automatically have a higher idle when cold, but not mine. Where do you think I should start?
thanks!
