UPDATE: I failed to mention in my last post about my cold start problems. When I come to my car in the morning, or after it has sat for about an hour. I will put the key in the ignition and turn it over and it starts to crank but won't turn over and fully start. If I turn the key back to the off position and try turning it on again it starts right up. Also, I have a misfire in cylinders 4, 5, and 6. I don't know if these problems are linked to the same thing or what?
