I'm trying to get my baby fully back in order. Gonna change a oxygen sensor tommorow morning. The jk is consuming to much petrol. Another problem I have is that there is a lot of heat comeing from under the car. The last time my shoes where boiling my feet. Any suggestions where the heat about.
A bad O2 sensor will throw a CEL, alot of heat under the Jeep could be a partially plugged Catalytic Converter.
