Two months ago I finally got around to fixing my Jeep which consisted of me changing the Fuel Pump, Catalytic Converter, Spark Plugs, Air Filter, both O2 Sensors. Before I had a Fuel System too lean reading, which led me to the Fuel Pump eventually. Since I had let it go for so long it had caused my CC to plug and that's why it was changed.
But now, the Fuel System Too Lean is coming back up on the computer. What else can I do??
