C200 Kompressor CL203
2003 C200 K - Low mipg, O2 error
Hi all.
My car, CL203 C200 Kompressor with 130.000 km, when in idle, is cunsuming lots of fuel. Dashboard indicator starts to raise whern idle, till 40liters/100km after some minutes, and also while driving its around 14liters/100km. Driving with light foot, no sport runs.
Here is what i did as mainentance last week:
_Changed cam magnets and sealings
_Cleaned up connectors from oil leaks(cam magnets, lambda, ECU)
_New coil on cylinder 3
_New spark plugs, NGK
After driving 100KM CEL is off, but mileage is very low, and using "ScanTool" on my laptop, i see "Fuel system: Closed Loop, 02 sensor malfunction".
O2 sensor, Bank1, Sensor 1: its always at 7.995 volts.
I'm getting mad with this. Any ideas please?
Thanks a lot for your help!
