1995 e420 check engine light
i'm trying to figure out why my engine is running rough so the problem is the check engine light is on and at idle the engine shakes. i used the obd1 code reader on my 38 socket connection and got these codes back. 3, 4, 5, 6, 8, 9, 10, 11, 13 and 18. the owner before me said that he replaced the spark plugs but the the issue still keeps happening. the code reader came with this website http://www.mercedescodereader.com/files.html. but i'm still having a hard time as where to start . i'm thinking codes 4, 5 and 18 is where i should look into since it relates to engine fuel delivery.

Wiring Harness Issues
hi, my understanding is that your vehicle is one of the W124 models with biodegradable wiring.
This fragile wiring breaks down most severely with the engine heat. You can search the forums for this well-known issue, and there are 2 excellent You Tube videos on the W124
wiring safety hazards.
