Fair dues. Ticks all the boxes then, except its failing on emissions then.
You need to get a code reader to read the existing codes. Without them its impossible to diagnose your problem.
Get those, and live data, and fix what the live data says is wrong. Codes put you in the ballpark, data points out the cause.
And as I said before , analysing the gases first is like getting a proctologist to examine your teeth. Its starting from the wrong end.
The only way a gas analyser is of use is if you were setting the AFR on a petrol engine on a tune up,or getting the correct stoich values in lets say an LPG
conversion on a petrol car.
Anything else is telling you what you already know, emissions are wrong. And multiecuscan can tell you why.
Of course you could mess about with everything until kingdom come, and maybe pass the emissions. But as a clinician you already know thats not the way to go.
