I had a similar problem with my 99 explorer. It turned out to be one of the O2 sensors in front of the catalytic converters. The car has four O2 sensors - one before each cat and one after.

HI..............
Check for any vacuum hose disconnected or damaged.
Check the condition of the air filter.
Check the condition of the hose from the air filter to the throttle body. for no escape of air., loose clams.
Need to check the fuel pressure, replace the fuel filter.
After if the fuel pressure is OK.

Replace the part that control the idle when the car is cold.
The name is : IDLE AIR CONTROL MOTOR.
But before check everything show above.

Thank you for use fixya.

My 1999 Ford Explorer Sport 4.0 SOHC will cold start and idle till the gas runs out.Will not restart unless it is floored and then miss


Sounds like upper o2 sensors are bad. May also be other things like a dirty idle air valve, fuel regulator, fuel filter, air filter, etc. Do all the maintenance then re-evaluate. And the problem with o2 sensors may not give you a code.

Why does my 2001 sport trac stall at a stop after a long trip


My guess, throttle positioning sensor is failing and won't hold when it's hot. this sets base idle.

any of those sensors can cause that but the best thing to do is scan it or check for a vacuum leak with a smoke machine.

2001 ford explorer sport,6 cylinder,rough idle and stalling....unplugged mass air sensor...seems to idle fine then...can u help me?


If there is a Auto Zone around your area, have them scan the Explorer for any DTC codes since it's fee of charge. But in the mean time buy a can of MAF cleaner and follow the instructions and also buy a can of Trottle body cleaner and follow the instructions on the can. Clean the MAF and the Throttle body, also try to get the Idle Air Control falve cleaned too which is on the throttle body. So use up the whole can of Throttle body cleaner and it would not hurt to use two cans. Once everything is cleaned that should fix the problem, the other thing to that would cause your poor idle and stalling is a bad or dirty EGR valve which can be cleaned with Carburetor cleaner since it's stronger then the Throttle body cleaner, just remove the EGR and spray the Carbon build away and place back in place. Note: the Carb cleaner is to strong for the gaskets used on the throttle body so don't use it on the throttle body. Good luck and this should help get your Explorer running 100% soon.
