Engine Stalling after Starting
Discussion
I've had my 2009 Mondeo 2.3 Petrol Auto for three years and it's been a fantastic car with virtually no problems at all with around 67,000 on the clock.
Recently I've noticed that when immediately after I start the car the revs will drop down and sometimes the engine will stall. Restarting then requires a little footwork on the accelerator pedal to stop it happening again.
The problem never occurs when the engine is cold, only after it has warmed up.
I was wondering if anyone can suggest what may be wrong and if it's a quick easy fix then I'd be prepared to have a go myself. Failing that it may need to go to my local Ford independent who are always pretty efficient and very reasonably priced.
Thanks in advance.

Maybe a minor sensor issue causing it to run slightly out of tune in the conditions immediately after starting up, and this is causing the idle speed control to misbehave. For example if that engine uses a hotwire mass air flow sensor, maybe it's contaminated and reading inaccurately at very low air flows. That's just an example - don't assume it's that and go changing stuff until you know what's wrong.
