hi all i have a 2012 volvo s60 with 130 miles,when the car is fully warmed up sometimes it shuts off waiting behind red light ,but it starts rightaway and seems to be ok after that also sometimes it hesitate during driving and then it go away.it happens randomly but usually after driving it for a while and fully warmed up.no codes .any idea of what it could be? thanks
You may have leaky fuel injectors. When the car warms up, the engine needs less fuel and if the fuel injectors are dripping fuel, it results in adding fuel while it is not needed. In higher speed, the engine consumes the fuel and you may not notice it but when you stopped and idling (let's say behind a traffic light), the engine can not use it and kinda flood.
thank you so much
