    Multiple engine fault codes after long drives

    Thanks for the ideas - I sent an email to Mark @Wranglerfix to see what he thinks. Tonight I got under the jeep and thoroughly checked all O2 sensors and the wiring seems to be fine (for what that means to my untrained eyes). During this, I noticed the ground strap going from the firewall to...

    How do I access the last two bolts on the oil pan between the pan and rear main seal?
