My engine light has been on and the reader says oxygen sensor. Recently while driving my radio will cut in and out. Just turned on my car and the power steering light was on. I shut car off and turned back on and the power steering light isn't on anymore but the engine light still is. While im at a stop light my car has a slight rumble to it, what is going on?

There are a couple dozen different codes relating to 0/2 sensors. What is the exact code number?

The other issues are unrelated and need to be asked in separate questions.

That code indicates that the engine is running too rich at idle. You will need to determine the cause of that and there could be any number of reasons for that.

Here are the factory flow charts.
