      Exclamation Engine Misfire issue

      My 07 Aveo was running rough for a couple weeks. I didn't think too much about it as I thought it was the transmission and figured I'd have to replace that soon eitherway. Today however it started lurching on acceleration and running terrible. It then started flashing the check engine light. I pulled into AutoZone and the reader said I got 6 codes P0300, P0301, P0302, P0303, P0304, and P0314. I don't know what's going on and would appreciate some insight. Thanks in advance.

      When was the last time the spark plugs were changed?

      My last car threw all those except the P0314. Turned out to be a burned out coil pack. But do check spark plugs first.

      I had terrible misfires too, but not to that extreme. Today, I replaced spark plugs (NGK), wires (NGK) and coil pack (Napa). Runs smooth like a baby's bum! But definitely check those first! And maybe other wires, too. I know there are some wires that are very close to the radiator hoses, and the plastic wrap melts and could melt the wires! Check everything! Lol
