2002 Pontiac Grand Prix, no power and sounds like a misfire
2002 Pontiac Grand Prix, so I was driving and when my
car shifted into 3rd it started to studder and had no
power? So I pulled over and checked the coil pack and
had no spark to the top two. So I replaced it and started it
up and still studder and sounded like a misfire. I am
wondering why is doing that, if it's a fuel filter or
something to do with the fuel. I don't know much about
cars. So anything will help thanks!
