Finaly got around to installing the new O2 sensor. Car was runnin rough do to the sensor going completely out.

The sensor i used is a bosch universal. All the wires are color matched as listed on the paper. But for some reason i still have a slightly rough idle. its not as bad as it once was but still there. car dose drive alot better and alot smoother threw the rpms.

I have a 2g gs-t stock 4g, stock smic, with injen IC piping and filter. new NGK plugs and wires, along with new coils.

Any ideas? car is auto

or should i drive the car for a while and see if a new tank of gas will burn some crap out. I will be doing an induction service later today.
