What are the actual AFR short/long term values?
If it's just high CO then it can be the cats not doing what they should. Could be o2 sensors but you'd see that in the readings. My gut says not the maf
Thats what he sent me

Do you have maf sensor related code?
Plug condition?
Air filter?
Plugs and coils done about 4-5000 miles,
Air filters done even less,
Random rich and lean codes in shadow memory,
No cat efficency codes,
Fuel trims il see in a bit,
It got about a 45min run too mot place and i used all 400bhp since i haven't driven it in over 2 month 🤣
 
At running temp
Air flows reading 5g/s at idle, (seems real low)
Short term fuel trims are at +9-12°
Long terms +1.56% on bank 1
And -3.12% on bank 2,
 
I think my p38 4.0 Thor was around 5g/s
Long term trims aren't perfect but not too far out to be a concern.. in my opinion
No dont think its bad bank too bank, maf under reporting would make sence of the short term trims and rich codes for both banks,
A maf and a pair of lambdas is easy to do there and got bought another set of wheels the same to throw on it a fail and 4 advisories on tyres yes i know naughty me,

If no joy with them its getting left with them too sort 😅
 
Joined the M23 from Gatwick heading towards M25 yesterday evening. Suspension fault, down to bump stops, managed to get to one of those emergency lay-byes. then waited for RAC. From 9:00pm until 1;00 am on side of motorway, then until 2;00am until recovery truck arrived, then in truck until 4;30am when they left us at a service station. We got home at 3:00pm today but my L322 is still at the services waiting for onward recovery, which they failed to do today at all. o_O Not feeling good about my car or the RAC at the moment!

There could be a air leak in the induction system 🤔
This can cause maf discrepancies and the short term fuel trims are above normal, they should be around 0+/-.
