Asked by bherna1 Apr 08, 2015 at 02:42 PM about the 2010 Chrysler 300 S V6 RWD

Question type: Maintenance & Repair

As i seen on this website my car is idling funny making the puffing nose in the exhaust
pipe.   Replaced the plugs on the cylinder 4 side.    Cleaned the connectors to the
ejectors.  My mechanic determined the coil is not bad.   I am taking the car back to
him because he eventually finds out the problem.    Is there anything to keep in mind
that this make and model of charger is prone to do in this event?    Just turned 100k.   
Its been a perfect carThanks and would appreciate advise Bernard

The majority of the time when you have a misfire with these type of systems it's either the plug or the coil
