The "service engine soon light" came on. Had the code checked at pepboys. Was told it's PO306, cylinder misfire. Would that mean it's most likely the spark plugs? All 4 oxygen sensors, & cats were replaced last year. This sounds like a new issue. Anybody have this code before & what was your problem? Thanks.

When was the last time you got a full tune-up? You may have a bad spark plug,wire or you got oil in cylinder number six spark plug tube causing a misfire. If you havent had a tune up done in a while I would start there
