Fault codes on C180 W202

[Tonymak]

I had a diagnostic done on my P reg C180 merc and it came up with 3 fault codes as below:

029 Lambda control is at rich stop misture too lean

035 Self adaption idle speed too lean

061 Shorterm self adaption part-load exceeded

I need help in translating these codes, is it major faults?

Thanks for the help
Tony

Just puzzled why the person reading the codes could not explain.

It's running too lean, but that may be just at idle in which case look for an air leak into the intake.

Hi kth286, The person who did the test was not sure of the solution for the codes.

Thanks Dieselman I will check the intake and have another diagnostic next weekend.
