my 2010 mustang GT will not start when outside temp is in the mid 90s or hotter. it has also had times where it is running and then acts like it is only running on half of the cylinders and just dies
car has been in and out of the ford dealership in Carrolton and has already had the fuel pump changed along with other misc. items and it just does the same thing when the temperature goes above 94 + or if its really sunny with little air flow
May be a bad mass air sensor
Perhaps a heat sensitive relay?
Bad fuel injectors or fuel rail. Had a Miata did the same thing.
It would be very rare for more than a single fuel injector fail at the same time.
