The Coil pack came and I installed it. However still getting a P0300 code. Did notice the ground wire was a bit loose. The EGR Valve bolts were ridiculously tight so I'm going to wait and see if it was the ground wire. Misted the wires and all was good there. Visually checked the vacuum lines, nothing rotten. new air filter, and did the valve cover gasket a few moths ago no oil in the spark plug wells. Also new wires and plugs. (Did put platinum plugs in) There does seem to be some opinions that a copper plug is a bit better for the Aveo.

Wondering if the cheaper amazon coil pack could be the issue. Or perhaps fuel pump. I know this post is all over the place but anyone who dealt with an Aveo with these issues will understand.

Thanks
