Multiple cylinder misfires
Chrsyler dealer admitting they can't help may be a blessing in disguise. Throwing parts at it (your expense) ,til it works. Has it started running straight again? Idling an starting? Was a one time rough start? Does it start then shake violent?
Misfire codes this time of year is normal WHHHHAT???????????????????????????????
If the engine is cold and you shower down on it hard youll likely throw a code !

This actually started about 4 months ago. Need to get light off, so I can maximize a sale price or trade in value. Lost my job of 25 years to a sale and don’t have enough liquid assets to be comfortable.
1st I would do is check all the plugs. If misfiring they will look different, alot can be told of a engine by looking at the plugs.
Then switch coil pack and wires from 1 2 and 3 with the misfiring 4 5 and 6.
Either pin point or rule out before throwing parts at it.
Run some good injector cleaner.
Do you have a laser temp gun?
After warmed up checking Temps from each cylinder and comparing, can tell if acouple cylinders are running lean / rich.
Mechanics stethoscope is good to listen to injectors and valvetrain while leaving covers on.
But if it runs good and never noticed a hesitation a sensor.

" Where should I start throwing my money? " well, if you have an Android Phone or Tablet then Amazon for a $12 mini Bluetooth OBD-II dongle and Google Play Store for Torque Pro ($5). Then run your own diagnosis.
I love mine, also bought for wife also.
Alright, I'll give! Please post a link to the dongle ( I laugh when I say it, I know how juvenile) that you guys think is best. I'll put this $1000 worth of diagnostic crap up. Your way is more, immediately convenient an I won't have to ride around with a laptop...lol
I thought I would cheer you up with a little laughter it's good for the soul , sorry to hear about your job loss but you seem like a resourceful fellow and I'm sure you'll bounce back. I like old school diagnostic work myself, it gives you a deeper sense of satisfaction when you figure out what the problem is and then come up with a solution to fix it.
