Emissions test help

[johndaily693]

Help originally I thought my O2 sensor was bad as I got an engine management light , please see the files attached , I managed to get a local garage supply me with some figures as good gesture. Do these figures look sensible ? Can anyone spot any odd looking figures and will this prove my oxygen sensor and catalytic converter is in good working order.
The natural idle co looks near the limit at 0.279 out of max 0.3 . The lamda sensor reading at 1.018 looks near upper limit.

Any opinions on the figures would be much apperiacted.apologies if pics are upside down, ipad shows them as correct side up before uploading.

I was once told "If in doubt, clean the MAF".

I used a cotton bud, some isopropyl alcohol & an extremely gentle touch- hey, presto the black wire became a silver wire & it passed the MOT with good emissions.

If you don't have a gentle touch, gently spray IPA into the MAF & let it drip dry.
