Anyone had an o2 sensor go bad causing the engine light to come on and engine to die?:cry:

It's possible. I blew the fuse protecting my oxygen sensor circuit so I was driving around with 0 out of the 4 working. Yeah, the car ran like sh!t.

Check all around the air intake between the filter and where it clamps on for cracks, etc.

an 02 sensor will certantly make your car run rougha nd in some cases not run at all. check for connections at the sensor and the fuse too
