Question about 2002 Ford Explorer
If it was a misfire it would do it in every gear not just 4th and 5th ....what you have is a speed sensor control problem. what this does is when the car goes into overdrive "on your car its 4th and 5th gear" it tells the ecu how much fuel to send to the intake...when this sensor gets tripped up it either overload the engine and put a check engine light on or it will go lean " which your car is doing" to fix this problem there is a sensor on the side of the transmission drivers side...disconect it and manualy go through the gears until it gets to overdrive...if it runs fine by that...then plug the sensor back in and head to the dealer and order a new speed control sensor....aka the one that shuts the car down at 100mph:) thats why i dont use em:)
