What causes multi-cylinder misfire in Mercedes-Benz?
1 Answers
Multi-cylinder misfire in Mercedes-Benz may occur due to poor spark plug contact, causing momentary ignition failure. Other possible causes: Excessive self-induced voltage in fuel injectors leading to sticking in the next working cycle. Poor heat dissipation of transistors in the ECU causing ignition coil malfunction. Insufficient cylinder pressure resulting in ignition failure. Maintenance approach: Check for aged wiring with exposed or leaking insulation. Reconnect and repair after confirmation. Replace damaged internal components of ignition coils or spark plugs after diagnosis. Manually reinforce all loose connectors. Inspect fuel lines for blockages causing poor fuel delivery. Check cylinder pressure and verify ignition timing accuracy in the timing system. Eliminate the possibility of using inferior engine oil that may compromise cooling and lubrication functions.
