2007 Sahara Unlimited
I recently replaced my radiator, thermostat, spark plugs, and wires. And some suspension parts up front, (Moog Ball Joints, Adjustable Front Upper and Lower Control Arms, Steering Stabilizer, Bearings, Rotors, and Pads). I have disconnected and reconnected a lot of hoses when it comes to the air system.
I got an engine light pop up on my way home from the shop and it scanned as P0420 Catalyst Efficiency (bank 1) and Another code popped up that said "Small Evap Leak".
I have been searching, but I don't want to start out looking at Catalytic Converters and O2 sensors if it could be something smaller. I have emissions due and I am tired of sinking money into this "new to me" jk and I want to try to pin the tail on the donkey fast.
All advice is welcome. Thanks!
