1993 Mercedes-Benz 300E 2.8L Poor Idle Quality, Surge
Posted to European Driveability on 7/19/2001 5 Replies

hi MB techs !! we searched in vain for vacuum leaks - reflecting on idle surge from 600 to 1100 rpm, but cannot find any leaks. could the mass air cause idle instability? other drivability on road is good !!
