I recently disconnected my battery to reset my ecu because of a check engine light (fault code was do to a bad o2 sensor) and i now have an issue with my idle. it starts up, runs great and drives like usual but now when i stop at a light or put it in park the idle drops. its like the car cant find the right rpm to rest at. if needed i can get a vid of it and post whats happening if that can help solve this issue. any assistance will as always be much appreciated.

You might of accidentally knocked out a vacuum line in the engine compartment. Check the vacuum lines
