Problems with o2 sensor? 95 318ti

[jon12545]

At the beginning of the summer my check engine light came up and after checking the code the 1222 error came up. I did not think anything of this as the check engine light went off and only seemed to come back on after I was driving the car for over a couple hours. Then recently when the driving slowly through a neighborhood, the exclamation point signaled on the dashboard and the engine stalled. After waiting for about 30 seconds the car started back up and I parked the car. Could this possibly be due to the oxygen sensor being bad? Any other ideas?

Plugged cat.
Bad crank/cam position sensor.
Bad fuel pumps/pump relay.

Swagging wide here....

Are they any step by step guides out there to change an o2 sensor? Sorry I am a complete newbie.

Jack up car.

Unplug O2 sensor cable. (O2 is on exhaust pipe by tranny.)

Screw out old sensor (I use a pipe wrench).

Screw in new sensor and tighten just firm, dont yard on it.
a LARGE crescent wrench works nicely.

Your done, put the car back down...
I literally did this in about 5 minutes at the autoparts store.
Drove the right side if the car up on a sidewalk using their driveway as a ramp.

BTW the manual and auto tranny O2 sensors in 95 are not interchangeable.
Wire is too short and plug is slightly different.

THE BLINKING " !" WHICH IF IT IS IN THE SHAPE OF A TRIANGLE IS THE TRACTION CONTROL.. WHY U STALLED NO CLUE?? BUT THATS YOUR TRAC CONTROL NOTHIN TO DO WIT SENSORS..

OK! Why you yelling?

yeah, I bought a universal O2 sensor off ebay for $30. I had to splice wires, but it was all color coded, it only took like 10 minutes, real easy.

I was getting the check engine light every now and then and my gas mileage went way down.
