Lately when I start my cobalt, the engine jerks a few times
like if it would be a starter problem before it starts, but it`s not the same type of sound
and it`s not all the time. Also the engine misfires very softly when it is in park
or while driving the car. I have been told it could be a problem with one of my
spark plugs or one of my coil packs.
Hope someone can help me solve this problem.
