C230 Diagnostic Code help?
Vehicle:
2002 Mercedes C230 Kompressor Coupe
I had the computer scanned and here are the error codes:
P201c- Misfiring Multiple Cylinders
P2036- Secondary Air Injection(Malfunction Air Flow too low or too high)
P0410- Fault Lamda Control
P0239- Recirculating Air Flap Actuator Adaptation Emergency Running
P2020- Engine AC Electric Suction Fan Fault or Short Circuit/open circuit
P0201b- Misfiring all cylinders
Can anyone explain any of these faults to me?

You need to take it to Benz to narrow down those problems. YOu need to find out which ones are current and which ones are stored. A generic scanner cannot tell you those things. You have a long list there and some of those things could be a one time fault.
Secondary Air could cause the misfire codes. The misfire codes could also be caused by wires (most common), spark plugs, coils, valves, etc.
But to narrow this down you might spend more trying to do it yourself rather than to just get an SDS scan.

I am going to start by replacing the spark plugs(the car has 110,000 miles and hasn't had a tune up), and see if any of these codes come back. Thanks for your help!
