No a bad O2 sensor will not cause bad idle. It is emissions related. One that is malfucntioning will throw a code, go to Autozone and have your car scanned for codes. To get everyone on here to help you more, what year is your car? Also, you might want to start with the basics; fuel filter change, air filter change, fluid changes, PCV and crankcase breather, etc.
