ranger, bucking, dieing, CEL
The codes pulled are PO171 and PO174 Banks running lean. The trucks a 1997 ranger 4.0 v6 AT. The truck only bucks when its warm. It doesnt buck very hard at first, it feels like its hitting multiple bumps in the road. It only occurs at speeds under 10 mph, like when I pull up to a stop sign/light. Eventually the car will die. If I put it into neutral and rev the engine it will not die. Just replaced the feul filter. Feul pressure is at 34. Is this too low? thanx in advance.
