MOT emissons
Hi guys,
Had my 2000 turbo 2000 in for MOT last week and it failed on emissons, it was about 2% CO. It had both cats on but it had a Prodrive pack on it with a prodrive ecu. I'm not sure if this is causing it to run rich or whether there is a fault with the lambda sensor or the MAF sensor?
Has anyone comes across this before?
Also, does anyone know the colour id for the lambda sensor?, ie which is which?
Thanks.

Sounds like a dodgy Lambda sensor, however getting the Cats hot just before the test should bring it into the right %.
Did they stick the car on the tester after idling for a long time or the car being switched off? Really need to rev the car for a minute or so before test make sure of pass result.
It 'should pass' with one cat on the car with the cat hot, they regularily fail when not warmed up enough (both cats)
