'96 SL320, '96 C220, '86 300E
I recently changed the spark plugs in my '96 C220, which I believe may have been original, and very shortly afterward I got a check engine light. The sole code came up as a "Misfire". Is this common after a spark plug change? The engine runs extremely smooth now and runs better than it has in years. Is it safe to reset the code and assume it was an anomaly if it doesn't return? I was told that a misfire code could result in cat-converter damage if raw gas is getting into it from a misfiring cylinder.
