Hi my Ford Fusion won’t stay running on the first start of the day ,I have to keep my foot on the accelerator until my rev counter works then my car will run ,but it is running up and down between 1000 and 1500 revs can anyone help please.
Throttle control sensor/ air flow meter. But what's also common fault is coolant temperature sensor. If I was u go to a scrap yard ...swap them out... If it does not work leave it there
