P0300 code
I changed the plugs, wires and the coil pack and I'm still getting P0300. I got i the code before the coil pack and it specifically said number 6. After the coil pack, the check engine light stayed off for awhile but it came back on for a random misfire P0300. Still has a rough idle and doesn't feel right.
