2006 V6 Shuttering-HELP!!!
 

:( 2006 v6 coupe 92k. Got a diagnostic when the check engine light was on, came up that it was the mapping sensor. Got it fixed. Got an oil change. The car has been shuttering and now that its getting colder outside its only getting worse. Mechanics don't know whats going on. Everything that's routine has been done.
