Scotty, I have a 2018 Jeep Wrangler JK Unlimited with the 2.0 L engine it usually runs great but lately I have been getting a check engine light with a P0172 Lean Fuel System, Rich code. Now, it doesn’t happen all the time, but when it does, How do find out what’s causing it and how do I fix it?

Start off by inspecting all spark plugs.
