Kind of related, we have a 14' as well and keep getting a P0306 code when pulling grades - right at 4500 RPM it flashes and if I let off it quits, if I stay on it light goes steady and get that code.
Dealer can't find anything of course, but ours is a misfire in Cylinder 6.
Could these both be Head related like in the 2012's?

Hey buddy hope u figure out what it is. Bummer.

I know this...sort of, my neighbor's Chrysler minivan had this code and there is a TSB (may be only for the minivan??) dealership replace the fuel float/sensor assembly under warranty, he got it taken care of a few weeks ago. Only reason I know about it he came over and asked me if I had received the TSB.
You should take it to the dealer and ask.

surprised they can't find anything...did they replace any parts? coil, plug wire, spark plug, injector, injector harness??? If they did a full trouble shoot they should have replaced parts, at minimum the spark plug on that cylinder. If all they did was stick a diagnostics reader on it when it was reading okay well.... I'd take it back and make them start doing a real troubleshoot.

Please disregard, saw pulling grades and check engine and thought they might be related, probably not after re-reading your code, sorry to go off topic.

Thanks for the response, didn't want to derail the OP's thread though - they switched plugs around I think to see if problem moves and did a compression check.

their next check will probably be the coil then the injector/harness. only reason I know is my neighbor is going through the same issues on his 3.6 minivan. I keep working him to let me do an engine swap since my 3.8 hasn't had those issues :cheesy:

Sounds like a short in the harness, loose connection or a bad sensor. This is in your fuel tank, not a harness or sensor on or near the engine.
From the interwebs....
The fuel level sensor is mounted in the fuel level sensor unit. The sensor detects a fuel level in the fuel tank and transmits a signal to the Engine Control Module (ECM). The fuel level sensor consists of two parts, one is mechanical float and the other side is variable resistor. The fuel level sensor output voltage changes depending on the movement of the fuel mechanical float.

Thanks Skid_Kid.
I gave up last night and was planning to do more research today. A coworker's car died on that same pass with a fuel problem. I pulled my code while waiting for them to get in my jeep. One thing I did different this time than the last time I checked codes was recorded a video of the display. Last time I did not write fast enough and missed some codes.
