    Hi, 2000 C230 K with worsening misfire. More prevalent when stopped at light, less when in neutral and not noticeable at speed. Also a deeper more guttural sound from the engine/exhaust? Could these issues be related? Maybe a back compression issue? Maybe plugs? I'm at a loss. No check engine light. No OBD codes x 2 scans. Use only brand name premium gas. Any ideas? Thanks
     
  2. No codes, no warning. I would do a tune up. Spark plugs, air filter and clean MAF. If the symptoms persist then you can dive deeper.
