If you mean the O2 sensors, they are in the exhaust pipes before and after the catalytic converter.

As the pin is in the bracket on the end of the switch you may be able to manipulate it if you can get the key and barrel out of the bracket around the steering column. Otherwise you will have to have the bracket removed from the column and fit a new one .

Is the rattling sound coming from the exhaust? I'm wondering if perhaps you have a loose catalytic converter. P0300 (multiple cylinder misfires) and P0306 (cylinder #6 misfire detected) are probably the cause as to why the car is sluggish, shakes, runs rough and lacks power. Make sure to take a close look at your ignition system (spark plugs, ignition wires, coils...). A spray bottle filled with soapy water can help you find voltage leaks on the wires and coils. Just spray the wires and coils and look for arcing. Replace any component that arcs. Other causes can be fuel injectors, vacuum leaks...).
