O2 sensor ok?

Post by HumblePie » Tue Sep 25, 2018 1:03 pm

I have been getting some oscillation in the revs and issues with co emissions.
Can you tell if the o2 sensor is ok with this idle image?

O2 sensor response is very slow (4 seconds). Normally it should be around 1.5 second or less at idle.

Well it made a big difference to the emissions test and brought it under the limits so this was a faulty sensor, and it was black when removed.
I dont know if you can see it on the graph below though, maybe because it wasn't fully warm when i took the screen dump.
