well got a 2000 ranger 4.0L... just last night on my way home it started stalling out at every light, and was idling well below 1000rpm.. any ideas? im thinking fuel filter but just wanna hear what the forum has to say and another problem is the 4x4, when i put it in the guage says im in 4high but only the back tires spin...now i dont know what thatmeans but its probably not good thx guys
