Hi folks,

I installed a Bosch O2 sensor in my car and the Check engine light came on. I tried to reset it by disconnecting the battery, and it stays off when I reconnect the battery and crank up the car. The light will stay off as long as I don't shut the car off. The check engine light comes back on after the car's been off for a while (not sure how long). I just put the old factory one back on and reset it (disconnect/reconnect battery) and so far the light has stayed off.

Has anyone had similar experience with the Bosch sensor?

P.S. I have an AEM/K&N intake (Short) and Apex'i WS Cat-back on my car.
