ok soo my car starts up fine and idles ok but when i start driving it stutters almost violently and even stalls out sometimes, the speedometer also acts really funnny, when it runs smooth w no probs the speedometer runs fine. then i notice it stops working and immediatly the stuttering starts, almost makes it impossible to drive. tried cleaning the maf sensor and that didnt work. took it to schucks and used odb reader and p0171 popped up.
its a 99 explorer 5 spd. 4.0 engine. the stutter is real band in first and second gear not soo bad in 3rd and 4th. anyone maybe know what might be causing these strange problems????
