EFILive Data - Need help I posted this on another board but haven't gotten any solid answers. I logged the following idle data for 10-15 minutes. The car has smelt rich for quite some time, and I'm wondering if this would confirm anything. When I watch the HO2S21 oxy sensor I can't help but notice how much of its time it spends in the lower portion of the spectrum compared to the H02S11 which fluctuates up and down as I have been told a normal O2 sensor should do. Could this indicate one or both sensors on one side have gone bad, or a possible problem before the 02 sensors? I have the log file if it would help. I've logged idle a few times and this is consistent behavior. During acceleration and normal driving both sensors fluctuate properly. I've got a smog check coming up in less than a month and I need to get her running clean. Thanks for any advice you might have!
