Question about Cars & Trucks
Fuel is metered to the injectors on a signal from the coolant temperature sensor. When the sensor fails the engine will be slow to start the first time and there is a strong odor of gasoline. Turn it off and it will start right up. There will normally be no code. Idle is sometimes affected. Fuel milage will be lower than normal

Fuel is metered to the injectors depending on a lot of information from several sensors.
It would be the height of coincidence for a sensor to begin sending wrong information just when a car is serviced and if that really has happened it is just as likely to be one of the other sensors as the coolant temperature sensor.
Clearly the first thing to do is to verify the servicing work has been carried out correctly and whoever did the work hasn't clumsily left a rag in the air cleaner or something equally elementary, such as accidentally knocking off the vacuum line to the fuel pressure regulator.
