Today I replaced the spark plugs in the car and replaced the driver side valve cover gasket. I did use dielectric grease on all the coils and plugs and noticed once I started the car it was running really rough. I pulled the plugs on the coils to narrow down which ones were causing the issue and it’s the two back coils on the driver side. I swapped them around to see if it would follow the coil and it stayed at those two connectors.
