Hi, check the wiring on the sensors for contact with the hot exhaust. The wire may have melted insulation (you may not need a sensor but just a wiring repair). The sensor is screwed into the exhaust pipe behind the catalytic converter. There is one on each pipe. Code 58 is bank 2, which I think is on the passenger side. The O2 sensor may possibly cause the other codes too, but I have a post on misfires you can browse.
Please see my tip at http://www.fixya.com/cars/r6715318-causes_gasoline_engine_misfires . These are generic instructions. If you get stuck or need specific instructions for your car, please get back to me with model, year and engine info. If the code 300 is not being caused by the sensor, then a tuneup may not resolve the issue. For example, a code 300 can be caused by the crank sensor, and that is not part of a tuneup. So $350 later you may still need more work.
Hello jameymccormi,
Before condemning the o2 sensors take care of your misfire problem first. A misfire can cause the o2 code. A p0305 should be a code for cylinder number 5. Pull the coil pack rail and remove number 5 spark plug and inspected it the gap should be .040 inches. Has it been a long time between tune-ups?
If it has it's probably time to replace the spark plugs. When installing them they should be torqued to 22 foot pounds.
After you replace the spark plugs clear the codes and see if the o2 sensor code comes back on a test drive. If not problem solved and no need to spend the money on something not needed.
