03 E55 Misfire When Warm - HELP!??
72k on 2003 E55, Code is misfire on #5. Replaced plugs and exchanged coil pack #5 for #6. Still misfiring on #5. Runs perfectly when cold for about 20-60 minutes, then CEL comes on and rough idle and low power. Plug wires all "clicked" normally and just wondering if anyone has dealt with this before. Any help would be greatly appreciated.

Wrong section. You want the W211 section. They can definately help you.
Sounds similar, however, to a problem on the 2000 E55, but replacing the coil helped. I'm sure someone can add info. Good luck
