Hi i am a Explorer Noob! i have a 2001 Ford Explorer Sport 4x4 with a 4.0 SOHC engine, it starts up when cold in the summer time but in the winter time it keeps stalling and i have to drive it like a "clutch " till it warms up. does anyone know whats wrong with it? i will be on this forum with many questions and answers.


my Explorer when i bought it in 2006 it had 138,000 miles now it has 177,387 miles on it and it still runs strong !

Welcome to this forum! I've moved your thread into the stock 95-01 section. Clean the MAF sensor, IAC solenoid, intake manifold, and the throttle body. Check the ECT sensor.

These engines have issues with the intake manifold gaskets. When it warms up they expand and seal.

Oh i see i cleaned the MAF sensor by the air filter and changed the IAC on top of the intake, also i replaced the throttle body sensoe where the valve is that opens and closes between thte filter and throttle body so i guess i need to replace the intake manifold gasket this summer.

whats the ECT sensor where is it?

The ECT is the engine coolant temperature sensor.

Idle air control.

Lower intake manifold gaskets are where I'd put my money.
