Plumbs Posted December 12, 2022 Share Posted December 12, 2022 (edited) Hi all , I think my o2 sensor has died . Ok so below is two data logs one down earlier this year and one just done now . So the one done earlier this year , at idle is logging as it should near 1 lambda . Now logged it tonight and the final lambda at idle is .81 !! But it’s showing 14.2 to 15.2 on the af gauge . It’s hard to start when it’s hot and I had to give it a little throttle which Is indicating a rich condition on start up “This is my Territory by the way .” It’s also running quite rich at open loop at 100 km’s showing 12 lts per 100 km’s and 14.3 to 15.1 .which has just started doing that . I’ve changed the low slope and leaned it out which made a little bit of difference. But the tune shouldn’t change. The low slope is the same as in the log taken earlier in the year showing near 1 lambda . So a dead o2 sensor ( original o2 sensor 2005 origin) would do this ? Also stalls in reverse if you accidentally punch the throttle. regards Graham. Edited December 12, 2022 by Plumbs Quote Link to comment Share on other sites More sharing options...
