Hi,
Generous Dad, thanks for that info. The engineer you mentioned, could you PM me his contact details if you don’t want to reveal which well known dealer it is.

Given that nothing untoward is happening - stable tickover, no power dips and anything else that might point to a more pressure issue, I’ll just see how it goes too. I was speaking to a car restorer whos specialty is Austin Healey about it today and he agreed. The TF certainly doesn’t lack any performance!
Cheers,
Michael.

Thanks Pharg for your reply.
Interesting that the site you linked to in its explanation of O2 sensor operation stated that the post cat sensor should be some reasonably stable value. Other sources state that it should oscillate as per the pre cat. My confusion continues having seen both types of traces from the post cat - the one above recently and the oscillation when it was freshly replaced.
Anyway I’ve just had a 40 odd mile blast and there was no sign of the MIL. I’ve also made a note of the mileage it came on at the other day, so I’ll see if what the mileage difference is if it returns. Some sources have mentioned around 100 miles and/or a few start stop cycles between the MIL showing itself. All in all it working perfectly so I can’t see what the problem is (famous last words….).
Cheers,
Michael.

Thanks Mike,
Your second point definitely applies to my MG! Almost to the point of asking myself ’why have I got it?’ Although I asked the same about my Jag XK8. Another thread perhaps.
The fact that there’s never been anything resembling adverse performance since this all kicked off pulls me again towards your second point. Thing is, after my Jag experience - scratched from passing motor and tyres spiked because I ‘parked where I shouldn’t have’ according to someone has given me a complex about using it and leaving it in car parks. This is not helped by an experience in my Freelander of having the OSR door smacked while I was sat in it! Apparently I’d parked ‘too close’ even though I was further away from the parking space marker than she was. Yet another thread subject.
Anyway, will go back to the tester and find out where they got their sensor from and maybe replace it, but until the motor starts playing up I might just leave it. 🤷‍♂️
Regards,
Michael.

 All,
As per my previous posts on this:
TLDR
Jan(ish) 24
MIL light on; codes say post cat sensor U/S.

April 24 replace post cat sensor from MGOC. MIL disappears.
May 24, MOT time arrives; fails badly on emissions. New cat (one sensor and cat from ‘Bitz) and BOTH sensors (second sensor ordered by tester from unknown company) replaced by tester to get through.

Now got MIL back with code P0420 - Cat not performing too well (or words to that effect).
see the attached live data from last journey with MIL lit.
Your thoughts on the way to resolve this issue would be greatly appreciated.
Cheers,
Michael.

Got one of these to cover up while I was replacing the hood recently.
There are two elasticated straps, one at the front, one at the back that stretch under the car. Did the job perfectly. Would recommend it. 👍🏻

Hi Psymon,
Thought you might want to know about as per below. Has happened every time I’ve clicked ‘submit’ since your upgrade. Doesn’t stop the post just appears. Cheers.
