on a morning i can get in the car and start 1st time then take my son to school come back to the car and it will just turn for bit if you give it a bit throttle it starts. just wondering what the prob could be ?????

took it to the garage and he thought the reason was the crankshaft sensor fitted new one and still the same was thinking could it be the automatic choke sticking or the sensor ??? if so how much would it cost cos i have noticed the fuel consumption is not to good if i put 10 in with the petrol at 1.17 a ltr i get around 40miles before the petrol light comes on and get 23 miles on the petol light thats as far as i have pushed the petrol light lol.
