Rough engine idle - Check engine light

Asked by Sep 08, 2019 at 02:06 PM about the 2002 Mercedes-Benz C-Class

Question type: Maintenance & Repair

My 2002 C180 Kompressor only driven 57000 km runs rough at idle. Check
engine light comes on. 5 or 6 times a cyclinder has ‘dropped out’ but restores
once I restart engine. Cyclinder compression has been checked and is down
about 130 psi on 2 cyclinder. Have now run 2 full tanks of fuel with Liquid
Moly = no change. Strong fuel smell often noted. Spark plugs already
replaced as a precaution - no change. I’ve owned a driven car since 23000
km. No previous issues. Seems to drive ‘normally however issue remains at
idle. Any ideas would be welcome. Shero1
