Started up the Jeep and got the check engine light with these fault codes P0303 ( Cyl 3 Misfire) P0151 O2 (Sensor 2/1 Circuit Low), and P0171 (Fuel System 1/1 Lean). Engine runs smooth and seems normal. My Jeep is 2011 with 52,000 miles and trailer queen. I don't drive it often on the road. I have gotten only the P0303 once before and the fault would go away after driving about 50 miles. I figured it was glitch from sitting in the rain for 2 weeks. I can't figure it out. Anyone else had the same issue?
