M50 running problem when cold....

["Bannon, Damian O'Keeffe" <dbannon@xxxxxxxx>]

> cold (Sitting for more than 2 or 3 hours) I must leave it idle for a few
> minutes before driving it.  It always starts and idles perfectly but when
> I try to drive it it bogs down and is very hesitant as if it's got no
> power & won't accelerate.  It is impossible to drive like this but after
> idling for a couple of minutes it'll be perfect....  It seems like it
> actually switches over after a certain duration, not like it gradually
> improves.  It was suggested to me that this may be caused by a bad temp
> sensor - Does this sound feasible or are there other likely causes?  If it
> sounds like a temp sensor, is this something I could check and fix/replace
> myself?  (I'm reluctant to bring it to the garage as they said they'd need
> it to be left over night so they could check it when cold in the morning).
