12 jkur, 3.6 throwing codes like no other. Has new spark plugs and crank position sensors. I have cleared codes and they come back. Codes, p0017, p0018, p0019, p0345, p0390, p0344, and p0365. They will clear for a few miles driving but then back on ,and then running like poop. Any help or common issues
 
It was throwing codes before hand. It needed plugs ,130k,and crank sensors was was replaced in hopes of fixing.

But you didn't answer the most important question did you use OEM parts? These Jeeps are real picky about what gets installed on them sometimes you can get past it and sometimes not.

All the codes were for camshaft and crankshaft sensors. I'll bet the Camshaft sensor or it's wiring is the problem.

Also cause of the camshaft sensor also said something about a oil plug falling out on the front side of engine behind the timing case.
 
Usually when I see a ton of codes all at once the first thing that comes to mind is a wiring issue (i.e. a bad ground or a short in the wiring).

***** Please Do Not *****
Imagine if you took your vehicle to a Mechanic or the Dealer and the technician did what you do and threw parts at it until the problem went away.

It's called a "Diagnostic Tree" and their $5,000 (OEM Code Reader) plugs into your car and reads what is actually happening at the time it's happening then they study their "tree" and even go to YouTube for help before picking up their trusty 10mm. .... but I have yet to see a post, anywhere, where the guy working on his own Jeep has ever analyzed before changing parts.

So, Please Do Not Throw Parts At The Problem. Save your money.
