Can't figure out this 2 codes p0171 p0172 ?
My 2004 Jeep had a check engine light on today. Codes P0171 & P0172. I check fir air leaks found none. Jeep is idling a bit rough. Very well maintained. Did plugs 1 month ago. Has been running good for the last 3 months other than a rough idle here and there. I took a video with my scan tool...- KJ Rocky
