Hello m8 in reply to earlier i had the AA out looking at the motor there and it seems to be the temp sensor is malfunctioning causing the car to think it is cold and therefore causing the car to flood itself by over dosing on the fuel there is a constant smell of petrol so i would advice you to look out for the smell of fuel on your m8s car and if you smell fuel it is prob the temp sensor.

fuel leaks are quite common on the zed as is the smell of petrol try smithy's fuel line kit to sort this problem

Thanks guys for the info!!
