Car was serviced at 95K with new plugs, oil, air and oil filters, throttle body cleaned etc. It is driving perfectly but every now and then it is slow to start. It does not take several turns of the key but it does turn over for an extra long time before actually firing / starting. This seems to be more evident when car is warm. Always starts without a problem in the morning from cold.

Could it be Coolant temp sensor or fuel pressure?

Any ideas much appreciated?

So it starts normally when cold but stall a little after warming up? say after you did a quick stop or so?

I have the same situation and changing the CP sensor fixed it. Do a search on Crank Position Sensor as it seems to be the culprit for cars that are 8 year old/80000 miles or older. It's also on the DIY section
