Emissions test
Discussion
Just had an emissions test done prior to the MOT.
Left bank running perfectly. Right bank passed but running much richer. Tester suggested a missfire. Any one got a list of things I can look at in order. Coil packs and leads are relatively new and I plan to put new plugs in. Anything else I should be doing?

How do people get through the emissions test? I managed to get through by massively advancing the ignition and reducing the fueling in the tested areas, and this was after taking the car for a run to heat up the catalysers to nuclear temps.
In the end the car passed on the tester's computer but it was getting too hot to wait for contection to the DVLA so the testing garage gave it a pass based on that.
It got through, legally, although not without a lot of hassle.
How does everyone else do it?

I did consider that but I couldn't believe EVERYONE had to go to dodgy lengths to pass. You don't hear of people failing and not being able to use their Cerb because they can't get it through, so I assume all (guessing) 600 remining Cerberas pass their MoT every year.
Does everyone go to a friendly TVR garage then? Doesn't anyone try to get through a more conventional way like I did? Is everyone too afraid to talk about it in case it devalues their car? To be honest, that last sentiment is why I wanted to get mine through conventionally because I felt that if I had to rely on someone else to bodge it through then I couldn't sell it with a clear conscience. I now know it's possible and I felt I could repeat the experience if called upon to so.

Good news passed the MOT yesterday with no trouble. Here are the emissions figures on the pass sheet: CO=0.07%, HC=141ppm, Lambda=1.03. The right bank also passed but the HC figure was just under 200max.
She has new coils and new Magnacore leads. I will check the lead resistances just in case. She is also getting new Iridium plugs next week. I'll redo the emissions test to see if it makes a difference.
