Does this sound like a faulty O2 sensor?


No check engine light, just wondering if my O2 sensors could be on their way out.

Rough idle, acceleration from idle is very poor. Idling has VERY bad bursts in warm weather, and the acceleration is twice as bad when it's warm outside (anything over 60 degrees F).

No vacuum leaks, throttle body is clean. I am thinking of replacing both O2 sensors as preventative maintenance anyway but am curious if they could be my issue.

I know I don't have a CEL but I've heard O2s can definitely be faulty with no CEL.
