What about the upstream O2 sensor? Any point in replacing that even though it's not throwing a code? On my Integra I replaced the O2 sensor years ago, even though it wasn't triggering the CEL, but afterwards I saw an immediate, fairly substantial increase in MPG. RockAuto has the actual OE part from NTK for less than $100 which seems like great price. Includes the harness, plug, and even the harness retaining clip.
