My S320 has 220K on it and the check engine light can on for my wife. She was able to get in home stumbling with no power. I checked the codes and it came up with P0303 and P0304.


Is this an issue with the center coil?

Those are misfires from the #3 and 4 cylinder.

I knew it was a misfire. I'm asking if the middle coil pack runs the third and fourth cylinder on the s320

Yes
