Mechanics, I have a 2008 Chevy Cobalt that i have been having an issue with. I have been having a misfire in #1 cylinder for awhile now. I bought a code reader after the check engine light came on. The error code is P0301. I first replaced all of the spark plugs. Still had the misfire. So i ordered and replaced the coil pack for the #1 cylinder. (I am assuming that the #1 cylinder is on the left if i am standing in front of and facing the vehicle). So i am a little unsure of how to proceed to fix this misfire issue. Any help would be GREATLY appreciated. Thanks!
