If equiped with an EGR valve,remove it and check for little pieces of carbon holding it open.Make sure the pentil is seated and no air will pass from one side of the valve to the other....Thats all i've got ....

| Post subject: | persistent p0171 code |
I have had my 2003 liberty 4cyl stick to the dealer for intermittent obd codes. We have replaced both o2 sensors, fuel filter, had the induction system cleaning, plug wires, plugs and I still keep getting the P0171 ( lean bank 1). I can't find a vacuum leak any suggestions would be greatly appreciated. The dealer has no clue what they are doing, they are just throwing my money at the problem in the hopes something will fix it -bunch of BS! thanks Al |
