c240 rough idle missing at idle
Ok my 2003 c240 4matic wagon 160,000km has for one week when you stop it idles very rough like its missing NO codes and it does not do it every stop but most times
plugs were changed 40,000km ago spark plug wires never changed orig MAF
after 1 week it did light a code cyl 3 misfire I cleared it and it has NOT returned if it does ill swap coils around to see if code moves
any ideas I don't want to throw $$ at it by just randomly replacing parts
