I can tell right of the bat.I am seeing 2 possibility
- dodge do have tons of recall or screw up that bury under pile of red tape.
- most likely a reprogram.
- 2nd. Ur problem is engine performance and emission repair L1 tech territority.
- tobe absolute. If this car is in my shop.I will definitely look at the scanner live data chking air fuel ratio, misfire, mass air flow sensor. To make sure that if it is a misfire. Either cuz by mechanical(valve train), ignition, air fuel.I will also hook 5 gas up ur tailpipe under a load and see if the engine is performing complete combustion at that particular range. After all hardware and data chks out.I would go thru all network and chk similar symptoms.
Since ur car is so new. We as an independent shop still just getting the beginning of 06' model.I would definitely place wireless electronic microphone and
zero in where the noise came from and start chking on all bulletin and chrysler website. Bear in mnd this is what a professional shop can do. Not u. Cuz car repair info is dime in a dozen. Only with enuff experiences and training can get infomations from everywhere and finish the puzzle for conclusion.
But I can tell u 1 thing for sure. Lookin at the O2 sensor on the scanner with live data at that rpm range will verify if u have a burn valve or else map sensor with vac transducer on an oscilliscope will verify a valve train problem. Keep me update. This is the most challenging case i've encounter on this site.I will follow up toe to toe with u. Just email me.
U also must understand. Our inevitable obstactles. There's a lot of thing I can't do or see when a car is not in front of me. As for now playing long distant internet mechanic. Be patient.I won't quit on u.
