Failed Emissions Test....Help!
« on: 25 April 2014, 18:24 »
Below is the print out for the emissions test, which my car failed on for the MOT. What can I do to get it to pass? I have not got a clue, apart from trying to bribe the MOT tester  :laugh:

Hi ya,

Your failing on CO pretty badly, so it might be running rich.

I'll phone the company up that did my tbe and see what they say about their cat.

I have only just had the car custom remapped, so I doubt it would be running rich otherwise it would of been pointed out.

Lambda readings look to high, i had similar figures swapped it for new and passed, i also run Miltek 200 cell sportscat.
Is there someone local to you that could do some logging to check the values of Lambda sensor

Thanks, I have a liquid cube device that has a function which does "Air Fuel Ratio ( Lambda)" readings. Will that do the job?
