Hey lads,
00 b4 legacy failed the nct today, 2 steering rack gaiters slightly worn and a track rod end worn, :doh: not woried about them will get them changed myself during the week :icon_blahblah:

BUT it passed the emissions on the high idle 3100rpm
Lamda 1.02 (limit 0.97 -1.03)
Co 0.01 vol% l(imit above 30%)
HC 24 PPM (limit 200PPM)

However on low idle 1440rpm
Co 2.83 VOL% (limit 0.05VOL%) :icon_hang:
hc 166ppm (limit 0ppm) :hammerhead:

any ideas on this lads? :dontknow:

Thanks
 
Seeing as she passed at high idle , but failed at the low ...
i would probably rule out the CAT...
maybe the MAF is gone ,

i was dreading this part of the NCT with mine , but thankfully she passed
 
Yea think the cat should be fine was thken off after th e test last time and i only put it on last week and car wasnt on the road since! :wall:
a friend of mine failed his nct in his silvia cos of emissions cos his DV was staying open? first portof call is change mine back to the orignal for the re-test but dont think that is my problem! :hammerhead:
 
Anyone come across this problem in an impreza or legacy before? :ponder2:

any help will be appricated :thumbsup:
 
Thanks lads, where is my lamda/O2 sensor located in the B4? is there one or two of them :ponder2:
 
Thanks :thumbsup: must have a look for it over the weekend if i get a chance, sunny days are busy days but not complaining :653:
