2014 hemi 6.4 rough idle
hi i have dodge charger 6.4L recently i notice my engine runs rough on idle. I try to take to a local garage and they said spark plugs and #3 ignition coil need to be change. so as unaware of it i follow what the mechanic advice replaced spark plugs and one ignition coil. after that my engine runs the same rough idle. so what i understand that all the parts that he request me to replace is not issue with my car. anybody can give me an advice or any similar issue like mine?
