I have a 2010 Pontiac g6 2.4 l eco tech I was
picking my daughter up from school when the car
started making loud noise almost like a miss fire
the check engine came on.jp stoped at a red light
the car started a jerk shaking us I changed the
spark plugs still doing it what could be the cause
since the check engine light is on, scan for codes. a local auto parts store will scan for free. if it is indeed a misfire, it might be one of the coils, the codes will tell you which one.
