I ask this because I went out today (was about 3 degrees), started the car and the engine spluttered between 500 and 1000 rpm for 30 seconds until I revved her a bit (seemed like the auto-choke didnt kick in). Was fine after, but its a brand new car, full tank of Optimax, all fluids nominal.
So are they just buggers in the cold or should I raise an eyebrow next time it happens?
