My car had been driving fine in stop start traffice for about 40miles on the motorway - however when i pulled of the motorway it kept stalling..it was parked overnight and did the same thing this morning for a little bit then was ok after a while - do i still need to take it to the garage and does anyone know what the problem could be so i don't get ripped of at the garage
