Rough idle
Every once in a while and recently more often I've been getting a rough idle when in low speeds and not sure what is going on because there no check engine light on. I've hooked up solus ultra and it looks like the O2s bank 2 is giving an erratic signal. Should I condemn the sensor or look deeper?
