2012 Wrangler JKU issues

Pull on the battery cables to make sure they aren't corroded inside the clamps. Sometimes they look good, but the corrosion is hidden.
If the O2 foolers don't work.
No issues with corrosion. Battery cables are new , connectors are new. Pulled off and on many times doing work on the jeep. It’s an 2012 and I’m trying to do all the things to get ahead of them breaking. Just this week I had to replace the dreaded blend door because it started clicking. That was a fun one!!!
O2 coolers on the way, I’ll post the results when they get installed. After that I will be addressing the small rear main seal leak. Checked all other options. It’s definitely the rear main. That will be real fun! Thanks .

Ok, time for an update. I took the jeep to a specialist (Jeep). I had a leaking rear main seal. They pulled the transmission, transfer case, etc. found out that the torque converter seal had been replaced with the wrong part. So a leak there as well. Replaced the seals. No more leaking there. Big wallet hit. Asked about o2 sensors. Turns out that due to my mistake I had the wrong o2 sensors installed. I put in Bosch sensors. Wrong choice. The 3.6 is sensitive to the brand of sensor. I need to replace with Ngk 361 and 362 sensors. I have ordered them and will change when they arrive. It has something to do with the voltage!
Moral of the story is . Don’t necessarily believe what a mechanic that doesn’t work on jeeps tells you. Take it to a specialist. A good one who has jeeps outside that they are working on. Not the one who is recommended on yelp, google, etc. found these guys by word of mouth.
I will update when I get the new sensors installed. Oh, by the way. The wife is happy now without the smell of burning oil from the leaking seals. That’s another story I’ll post later. Thanks all for their suggestions and advice. I appreciate it.
