Need some help with a fc:(
 

Heres the problem. lately when driving the car it will just stall, like pulling into a parkin spot with the clutch in the car will die(not always but sometimes) or just pullin up to a light and pushing the clutch in it will die and on hotter days the car will sometimes buck when your driving and miss abit. The car has a brand new motor in it and i have no idea what the problem is. If you guys can help in anyway that would be great:)

Thanks.
Chris
