OK, as some of you remember, I had some concerns about my engine's behavior following a transmission and water pump replacement a couple months ago. I've been looking at Torque from time to time while on the road, as well as looking at other people's threads and screen shots when I noticed something today... My upstream O2 sensor, while it does oscillate (most of the time) it doesn't appear to be doing it anywhere near as quickly as I've seen it for others.
Managed to record half of my morning commute, wanted to see what others think about this. Here's a couple quick notes:
:32 Idling at a red light. O2 sensor movement not oscillating, but steps
1:00 leave from stop
1:12 Falls out of closed loop due to engine load (never seen this before)
1:19 Back into closed loop
2:00 Falls out of closed loop due to low temp for 12 seconds
2:17 Decent length of forward motion, stop and go traffic the rest of the way
Also, the knock counter usually pops up with some number at the beginning of my drives and it stays at that value until I got to my destination. But this time, continued to increase periodically. Should this be a concern?
