I know on the 3.8's there is supposed to be a paper shim stuck on the end of the cam sensor so it has the proper gap. Does yours have that when you installed it if the 3.6's use it?
OP
I just read about it and the 2013 doesn't use a spacer paper, but it says the ECM needs a relearn if replacing it.

At the end it says to disconnect the negative over night. I'm gonna try that. ThanksI just read about it and the 2013 doesn't use a spacer paper, but it says the ECM needs a relearn if replacing it.

I wondered if maybe you didn't do a reset, most of the time when doing electrical R&R you need to.
OP
No I didn’t reset it. But I have the battery disconnected now and I’ll reconnect it in the morning before work. Thanks

It was the Cam Sensor. I replaced both of them. I disconnected the Battery over night to reset the computer. I'm gonna pull the trailer to deer camp and mow. If the same thing happens I'll just unplug my trailer lights and hope for the best. And mess with it when I get home. Hey Thanks for Help. I've never been on a Forum before. This is cool. Thanks Again
We like helping people as long as they let us know there problem was fixed and what fixed it. Thanks

I tried to drive my Jeep to deer camp with my trailer and before I got out of town the ESC Light and the Engine Light came on and lost power again. I pulled over turned off the ignition then turned it back on the ESC light was gone. So I unplugged my trailer lights and it happened again just a few miles down the road. And another thing it seems to be happening at 70mph. Got off of the interstate and drove about 60mph and the ESC light didn’t come on. Any ideas????
Try doing what I suggested on my post no. 15 on this thread. https://wranglerjkforum.net/threads/2011-jku-sputtering-on-cold-start.26250/#post-427075

Thanks, I cleared the engine light. so I'll have to try to pull the trailer again soon.
