O2 sensor reading HELP

Ok my mot / nct failed me on reading of 1.07
All other readings are low idle 800 rpm Co 0.00 vol% HC 11 ppm
High idle 2.760rpm lambda 1.07 Co 0.00 vol% HC 12 ppm
Now my dataloger says my lambda is good jumps from 08 to 90 with nice wavelength.

Would that reading be saying that I have a little leak in my exhaust ?
The limit is between 0.97 and 1.03 , I'm at 1.07

Thanks in advance for your inputs I have it booked back in tomorrow at lunch and am taking it to a friends garage in the morning.

Either a leak in the exhaust or the engines alittle lean.

Yeah bud , just back from mates garage and we fixed a leak at back box gasket, she was blowing good,
Hopefully that sorts me out for test today ,
Fingers crossed, I will update how things go ,
Had to put my original steering wheel back on lol
Feels very strange driving with it .
Thanks jesse.

@jesse888 all good , she tested well.
