2014 Jeep Cherokee Latitude 2.4L
Hello everyone,
My fiance purchased a Cherokee about a year or so ago, and we have ran into issues that I am at a loss for diagnosing, as I have never worked on anything FCA.
Background, not current issue - Every once in a while, (I think it has happened 3-4 times every few months), the car has stalled, required her to stop driving and throw it in park, battery light coming on.
Background, not current issue - Along with that, the parking brake tends to randomly engage every few weeks.

Finally, we got an oil change on Saturday (2/8) and later that night when we started the car, it started misfiring, and the check engine light came on. We felt the extremely rough idle, and she had to go to work, so she drove it. Above 40mph it stops misfiring, but every time she starts it after sitting for a bit (after it cools down for a few hours), you can feel it vibrating very roughly, and what definitely feels like a misfire.
I am at a loss, but I read the codes, and here is what I got:
Current Fault:

• P0003 - Powertrain
• P0300 - Powertrain - Multiple Misfires
• P0301 - Cylinder 1 Misfire
• P0303 - Cylinder 3 Misfire

Historic Fault:

• P1065 - Powertrain

Any help is appreciated. I was thinking of moving the cylinder 1 ignition coil to 3, and seeing if the code changes. Is this the correct first step? My main concern is settling this misfiring issue so that she can drive to work and school still. She is still driving, but I don't have any solution for a temporary car, so I'm trying to diagnose and fix as quick as possible.

This is the newer "KL" forum - you want to change your personals from the older "XJ" Cherokee

I'm confused at what you mean. Sorry, I'm new the the forum. But I thought the board I posted in was for the 2014+ Cherokee, that's what I'm inquiring about. Could you by chance link me where I should be posting?

Your post is fine - your personals (listed at the far left) show you own a Cherokee (XJ)

Thank you. I didn't notice that on the mobile version so that's why I was confused. Logged in on PC and now I understand.
