Hi guys back for more help . Bought a micra today and it ran pretty ok in the test drive so i got it. stopped on the way home to get petrol. on coming out of the station i could smell petrol a bit but not much and about a minute up the road the check engine light came on. got it home ok and i let it idle for a while and it nearly cut out just once. would appreciate if anybody could point me to a common problem? I had driven it for about half an hour before stopping for petrol and it ran perfectly. i am 99% sure it wasent diesel i put in.
