    I called Ken. He said very unlikely it's the pcm. That's good. Turns out I used to work with Ken at the old dodge dealer in town. Had I known he was on his own I would have talked to him sooner. I plan on messing around with it a little more. If I get know where I will schedule an appointment...

    I'm not ready to throw in the towel yet.It has to be a simple solution. All the problems have got to be originating in the same place. It's not mechanical. When all the electrical components are working as they should, it runs and shifts great. I just have to keep plugging away. I have a 2013...

    HatterMT, I would be in for a second opinion of a guy that knows these engines. J4 is a great group of people, nothing against them.

    Yes I agree. I'm just getting tired of driving it after a repair and everything seems fine. Then the next time I get in it another sensor goes out. Another option I have is to replace all the O2 sensors. Then hope that solves the problem. I guess that may be the best route. On the other hand, I...

    Did a little more research. I'm thinking ntk makes the mopar O2 sensors not denso. That's what I put in. Also the other ones are ntk. I took my liberty back to the shop. They just called and said all the grounds look good. They are telling me the cpm could be the problem. I was afraid of that...

    What did you do to your jeep today?

    Today I replaced O2 sensor upstream bank 2. It's one of the easy ones to get to anyway. Friday replaced the ambient air sensor also had new windshield installed. Just got back from driving the crap out of it. They are fun to drive.

    Update... Everything was great for a couple days. Then it finally threw an engine code. Turns out it was the ambient temperature sensor behind the grill. I replaced it. It's fine now. Jeep is for sale

    I may have made a rookie mistake... I got this jeep at an auction, with a full tank of fuel. I've been having all these problems with an unknown fuel. I have know idea how long this fuel has been in the tank. I did take it down to the local shop. They did a fuel pressure test. 58 psi. Spec they...

    Thanks for the reply. Just got back from driving the crap out of it. It never stalled, but did notice a slight stumble a couple of times at stoplights. My thoughts are leaning towards fuel related as well. I was thinking it could be a weak battery, but I dont think that's the case. It was -4F...
