Apparently my car is misfiring and I need to replace my ignition coils and spark plugs.... when I start up my car or even when I'm driving.. It's super loud and not the regular deep smooth idle it used to be- now it's sounding like a super charged lawn mower! Could it be something else or just change coils and s.plugs? What is the best ignition coils and spark plugs to use for an se-r? *06 Altima se-r 3.5L 6spd manual trans

Loud usually means exhaust leak.

Misfiring can be a few things..what codes are you getting?
