03 SL500 REPLACED SPARK PLUGS, COILS STILL MISFIRES ON 1 WHAT ELSE?

Posted / edited by AnonymousUser on : 20-11-2017

Answers :

Switch spark plugs, ignition coils and fuel injectors from cyl 1 to 3.
See if misfire goes to cyl. 3. If that happens replace the damaged part.
If is still on cyl. 1 check the compression of the cyl. 1.
If that's ok see if the air mass sensor is working fine.
Also check if there is oil in the plug of the lambda sensor.
