I found this hose disconnected. What does it do and what is it connected to. Any idea if this would cause the car to fail emissions ?
Emissions, wouldn't think so. It is for fuel vapour....container on right side is a charcoal canister.
What did the MOT tester tell you? If you don't know posting a pic of the figures might help.
@kx3210 Hello and welcome BTW.
maybe say hello in the newbie section.
Do you normally run it without the rocker cover, cover?
Is it new to you?
Has it passed before?
Any changes to zorst system?
Vac leak?
Cat up to temp prior to test?
O2 sensors would affect emissions.
I take it there's no engine warning light? I suppose not, as that would be a fail. A bad O2 sensor will trigger a warning light, so it's almost certainly not a sensor.
That leaves the Mass Air Flow meter (which won't trigger an engine light) an air leak in the exhaust, or a catalytic convertor that has reached its sell-by date.
If you still have the cat it left the fsctory with, then a duff cat is highly likely.
Please post a pic of the emmissions read out that the tester gave you as that will enable us to give better advice.
Also if you get and OBD dongle and a phone app like Torque Pro, you can post any errors it comes up with.

Not neccessarily, prior to a registration 1st July 2003, it's not a failure.
Just to add, was at operating temperature when they tested it? It does help if it's had an Italian tune up just before the test!
Hi - Tried again and it is still no passing emissions. CO is 2.050, HC 373 and lamba .979 The mechanic says is running far to rich and suggested the cold idle sensor? may be causing the problem. He said it wasn't likely to be the injectors. It runs well and you can hear the revs drop once it is heated up. It has a new lamba sensor after the cat and a new cat. New plugs, air filter.

Have you pulled the plugs and seen if it's one cylinder or all four?
My 1st thought is the MAF, Carolyn mentioned it above. You could try cleaning it, but if it's running badly rich, maybe needing to replace it.
Sometimes priced high, but here's a bargain..... https://www.ebay.co.uk/itm/146529449077?_trksid=p2332490.c101875.m1851&itmprp=cksum%3A146529449077cbb14eade87f42b095d2eb844023768e%7Cenc%3AAQAKAAABEEjF85BqxvDZ1jWN0M7ZZP%252FwIxIyxxibX1jAgqeu0u%252FpLrxjXJzZi332RUIOaicEkrNSGEaHe7Xunz4brOLXFMJ8gyo6dIYDUc2pAJyyu2J6vN7ZMrqxJRk%252Fo9uxPzk5BjSDS1dxcWGsLMtYf49%252FAlJX2WUvHDFy2oKQIQkwHGzkyOX5VW1BbABybev0348asbHw1JSUUunKUr9KGmIcWWDVI64mUmjSUWVeOpCcOevBytAMVqPjqdR77Xv4Qe4BNtkCJIxpc%252B132vnDyZ0HoBY2%252B7%252FcDyzVVaN40N4B6dx8QVlt2lUaImz4WlmHrEf0IB82clLSH%252FkNT66pmoqOoLbDlhLcurScBO0L1gZhTIFf%7Campid%3APL_CLK%7Cclp%3A2332490&epid=1509578019&itmmeta=01JT0Q9T159YNE3ATYC49677PZ
Hi - Took the plugs out and they all have soot round the body of all the plugs, they are all new.
Got hold of a Launch scanner and got this list of reading. Anyone know if these are normal ?

No expert. But the above looks the stand out to me.
Was going to suggest anyone local you could try swapping a maf with. Looking at your profile. Perhaps not.
No expert either, but if all 4 are black maybe that Post cat sensor reading may refer to the rich exhaust. Maf is first thing as previously suggest by self & Ardent. I posted a cheap one link above.
MAF
Hi - have ordered a new MAF. Was wondering what the reading was O2FT B1 S2 99.155% manual says it should be 0 +- 20%

Link I gave you?
Last time I buy from a link on here. Ordered a MAF from the above link last week and it was supposed to be here by now but hasn't
even been shipped yet. Haven't even had a response from my 2 messages asking where it is.

Hey - stuff happens. Please don't blame the club for a supplier letting you down. 99% of the stuff on here is accurate, relaible and helpful.

Don't take the hump at me. As Carolyn states above, I was just the messenger (who put in the effort).
Have you reported it to ebay?
@kx3210 From the link, kindly provided by Gaz mr-s please refer to the following:
Located in: Dublin, Ireland
Delivery:
Estimated between Mon, 12 May and Fri, 16 May to GL11AD
That is from today, that means 5 - 9 days delivery time and that is from Dublin, S Ireland / overseas!
I have mentioned previously that persistence is one of the best tools in the tool box. As can be patience.
PS: Not to mention a weekend and a Bank holiday since you ordered on April 30, per your post at 22.00 hrs.
