Emissions... Just can't pass the MOT
Hi
A while ago I posted these results:
Test One:
fast Idle test Limit Actual Value
CO =<0.2% 0.51%
HC =<200ppm 38ppm
Weird symbol 0.97-1.03 1.004
Test Two:
fast Idle test Limit Actual Value
CO =<0.2% 0.41%
HC =<200ppm 22ppm
Weird symbol 0.97-1.03 1.002
Natural Idle Test
CO =<0.3 0.12%
Since then, I have changed the sparks, oil, oil filter, air filter and fuel filter.
Its running really nicely, but still failing on emissions. The CO is still too high. The car is a turbo 2000 with PPP so just runs a single sports Cat.
Having now serviced it fully, do I need to accept that the Cat has gone?
It was fully up to temperature at the time of the test.
I can't think what else it could be.

Terraclean! Takes about an hour and supposed to cut the emissions to at least half of what it is!!

My car has PPP and needs to be ragged mercilessly for half an hour before the MOT
Drive stinking hot straight in to friendly MOT examiner with probe at the ready, and passes every time

Yep. Made sure it was up to temperature. It was a 25 mile trip to the garage. The garage were waiting for me with the emissions test probe
Terraclean... Cuts emissions in half does it? Doubt it.. Every additive I've ever tried doesn't work.
I think replace the Lambda next...
