Took my mk6 Honda for MOT this week, overall it passed, but examiner said that he doubt it will pass next year on account of failing the Fast Idle Test.
Co was measured as 0.41 % vol , (Limits max are 0.2)
Second Fast idle test
CO came in at 0.01 % vol
Was advised it could be the lambda sensor or cat that needs changing.
Any advise on this would be appreciated.
attached are the results from the mot
