car failed mot on lambda reading, was 1.12 first test, then 1.05 second time....
what will the cause be,...its a fresh import, and tester didnt fail ex system, but issued advisory due to cat noisy,..but no holes...
could it be simply that the car is running too rich..?
and if so, how do i adjust it...
btw, new cat coming as it needs replacing anyhow, just want to make sure it passes...
