My Explorer has a problem I and other friends cannot solve. It runs fine when the weather is cool out. When it is hot out and the engine has warmed up, when you stop at an inter section and step on the gas to go it will stall. After about 30 seconds it will start up and run until you step on the gas again. If you press on the gas pedal and accelerate slow the Explorer will start moving again until I reach traffic speed. If you step on the pedal hard it will stall out again. Yesterday in Tucson it was 108 and at every intersection it would stall after I stepped on the pedal to go. No dash board lights come on and my scanner shows no error codes. Checked the fuel pressure and it is around 60 lbs. I had the thermostat housing replaced with a new thermostat, engine temp sensor and temp gage sending unit replaced. It did not help. Any suggestions

Too many variables need to be checked before condemning any part.

Injectors woukd do this when hot.
Tps would fail too
Cam phaser solonoid
O2 sensor and the list goes on

This condition could never be isolated without using a scope.

I Hope this helps
Good luck..
