idle help

[imof6]

I've recently had an Inspection II. Afterwards I notice that the idle is around 550 to 600 while it is still cold ( the temp needle has just started to move ). Once warm things are much better ( 750 to 800 ) but I still can get the occasional stutter when starting off from a stop. It didn't do this before.

Also when starting up from warm the motor doesn't catch as quickly as before and there have been occasions when it actually died on me and I had to start it again ( I never touch the throttle when starting ).

I'm starting to fear it may be something like the MAFS. Any ideas guys?

I definitely agree on the mass airflow sensor. I work on many bmw's and from an over the internet diagnosis...lol that is what i would put my money on.
