Need help !!

The wife's corsa just failed mot on emissions..

Heres the faults.
•Engine Mil inoperative or indicates a malfunction [ 8.2.1.2 (h) ]

•Exhaust lamda reading after 2nd fast idle specified limits [ 8.2.1.2 (c) ]

Heres a bit of extra info.
We bought the car a few months back . On the way home after buying we noticed the management light come on but the car drove fine..
My cheep tester said bank 1 lambda on the manifold.. the lamda sensor did look new but almost cirtainly a cheep after market as the wires were far to long..

Anyway we bought the original vauxhall landa sensor from vauxhall ( not cheep at over £200)
,reset the management light and it did sort of do the trick.. ( no light reappearing atleast) but it started to drive with a flatspot which it didn't have before with the cheep after matket sensor, ( which would drive fine without a lack of power but the light would reappear within 10 minutes of resetting) .

The new landa sensor the light doesn't show on the dash but a lack of power in low revs but roughly im guessing after 2K revs the car picks up with great acceleration.

So whats your feelings on what i can do/check ect??
Thank you everyone if you can help

What year is the corsa as if its before a set year the mil light is not a fail, a lot of testers don't look at the year for the fail.

They didn't give my wife a readout or printout sadly so i can't say if high or low reading..

Some one suggested that it might have a small leak in the exhaust which it has come up as an advisory but its the rear of the exhaust..
Could that still be an issue in your opinion?

You need to ask for print out, they must give you a copy by dvsa rules.
