Hi Everyone,

 

So its MOT fun time again, it failed on emissions:

 

Fast Idle test:

CO - 0.03%

HC - 11ppm

Lambda - 1.05 - Fail

 

Second Fast Idle test:

CO - 0.08%

HC - 11ppm

Lambda - 1.05 - Fail

 

Natural idle test:

CO - 0.03%

 

So I dusted off my trusty cheapo ebay OPCOM and I am getting this once the car had warmed up:

 

 

b1-s1 02 sensor - Jumbs between 52mv - 811mv - rich/lean - (hovers approx 50mv at 3.5k revs)

b1-s2 02 sensor - approx 22mv - rich

 

Can anyone point me in the right direction?

Also had this code in there but I think it may be old as the scangauge hasn't shown me this:

 

P1171 - Fuel Supply System Lean During Power Enrichment

 (00) - Not present

A shade lean. Try bunging up the other tailpipe

Thanks Slindborg, I will get them to do that. I was thinking of taking it for a bit of a run to get it warmed up but I dont think that will help with the lambda reading?

Passed but not without drama, they were about to fail it when I stepped in and got them to test it again. It just scraped through, I will be finding a more understanding test center for next year!

Oh also forgot to add the tester refused to block one of the exhausts saying "well that's not how you would drive it on the road!"

sounds like you need to find a new MOT man

 

Last year the bloke refused to get in mine as he wouldnt get out so I did it, well the inside bit, 

 

On the rollers, brakes, lights etc.. haha
