Mass air flow sensor has failed 5 times since 1999. Vehicles stall at low/idle speed at intersection putting driver exposed to rear and side impacts. Daughters have had near misses this year as they were using the vehicle to go to summer school in phoenix. The vehicle also looses power momentatrily at high speeds. Rpm drops but it kick backs up again. Problem is intermittent, and usuall happens in the summer when the temperature gets high in phoenix, started in 1999 and changing sensors has not helped - happens every summer. This time I noticed the ammeter gage go south when it indicated a loss of power. The vehicle starts right back up after stall when you crank it again

This vehicle will stop running, no sputtering, just lose power, at any speed, at any time during operation. Once, vehicle even reset the radio stations, as if the battery had been disconnected during service. There is never an indication that the vehicle is going to quit. It then takes about 1-2 minutes to start. The engine will turn over, but will not start until you wait, with the key off, for the proper amount of time. The radio still works, all electrical components still operate. This has been happening since I got the vehicle. I have written to you once before concerning this subject, but never heard back. Please respond to this complaint. I appreciate and anticipate an answer. Thank you. Jamie urquhart.

Engine suddenly stops while in operation. When this occurs, it is typically during low speeds or while turning onto another street. Also, during high speeds, it feels as if the engine will lose power, but will not shut off. A private mechanic was able to reproduce defect, and they replaced fuel flow valve/control in an attempt to repair the defect. Approximately 2-3 weeks later, engine would begin stalling again. Please provide any additional information/attachments.

While driving into an intersection the eec system lost power and the engine turned off no one was hurt replaced power relay no problems since. It also appears that ford made some changes on the relay they might know about the problem. I wish they had told me I could have been killed at that intersection.

While driving the vehicle, it lost power. We had to pull to the side of the road. To proceed we had to floor the car just to move. At the dealership in nc we waited and then the car worked perfectly. Vehicle repaired in sc - idle air control replaced. Two hours into driving the same thing happened. Vehicle taken to larson ford - lakewood nj several times.replace thermostat reprogram PCM;replace fuel filter; replaced pfe and egr sensors; replaced engine temp sensor and PCM; a computer check was done prior to the replacement showed nothing wrong. In june 1999 a trip of four hours on the pa turnpike the vehicle did the same thing: loss of power the thermostat gauge moved to the right of the indicator (as before) . After waitin for about 15 minutes the vehicle worked okay for another hour. And then the same thing happened. On the way back from pittsburgh we stopped periodically with no problem. Larson ford checked the vehicle and found nothing wrong although a computer check found several things wrong but they didnt know what to fix or "replace". When I called the manufactures customer service they told me that there was nothing that they could do and to bring it to a dealer. As far as I know the long distance problem with this vehicle still exists!!!

Explorer engine light comes on after combination of 1) driving on highway for approx. 1 hr and 2) have to climb a large hill...approx. 5 miles at 60 MPH. Truck stutters and bucks while cruising at 55-66mph when this happens. Truck was diagnosed approx. 10 times. I have all documentation for trying to resolve problem. Truck has shut down completely during one of these episodes losing power to steering and braking. As a parent of two small children I'm even more concerned. Dealership tried replacing fuel pump(2x), tp sensor, potentiometer with no fix. Dealership said it could be oxygen sensor, mass/map sensor, throttle control at one point but later changed mind. I know of one other explorer with similar problem. I hope this adds to your list. Please let me know if you have any information.
