    Failed MOT due to emissions - high CO (EDIT: NOW PASSED)

    By means of update, I wanted to share I opted to swap out both lambda sensors while I have the money and inclination (enthusiasm ;)) to do so. I bought NTK sensors from ‘Parts in Motion’ as follows: NTK Lambda Sensor 0277 - £109.82 NTK Lambda Sensor 0266 - £81.58 (Prices incl. VAT and before...

    Well, hello there!

    Thank you - sad to see how much havoc scrappage has wrecked on cars at this end of the pricing spectrum. This is exactly the type of car a new driver needs…but decent cars like this are very (very) rare and many of those those out there are **** piles.

    Failed MOT due to emissions - high CO (EDIT: NOW PASSED)

    Thank you both; you echo my own thoughts and those of mechanic and MOT tester. Trying the fixes in order of cheapest first, and as I have a pathological need to ensure my cars are properly and correctly serviced, I serviced it myself with all genuine bits incl. all filters and plugs as well as...

From my basic chemistry (HAHA!) given how high the CO is, I am leaning towards the CAT not working as it should (or not at all) as it does not seem to be catalysing the CO into CO2. I...

    Failed MOT due to emissions - high CO (EDIT: NOW PASSED)

    To be fair, the CO result is not surprising as the car does smell as if it is running a little rich. Have tried the old Italian Tune Up with a can of Seafoam into about half a tank of Tesco 99 fuel. I completed a 50 mile drive in third, revving to 4-4.5K revs at 65MPH, and it was retested while...

    Well, hello there!

    Hi Forum, I have acquired a 1999 (T) plate Honda Accord 1.8i ES (Auto) saloon for my son who has recently passed his test. We hope to DIY a lot of the basics ourselves and, thanks to the forum, we have already ordered a whole bunch of stuff from COX Motor Parts. As it happens, the car has...
