Driving the vehicle in this condition will only cause poor fuel mileage. So you can drive it for a few weeks until you can get the issue fixed if the time is needed..

Sounds like you have a faulty catalytic converter on your exhaust. At 75,000 miles, it is not a bad idea to get the plugs and wires changed. Oil and filter should be changed every 3,000 miles. The 02 sensors will cause bad fuel mileage when faultybut would not cause a smell. I suggest having an exhaust shop look at your catalytic converter(s) to see if one or more need replacing.

Unless you know welding, there isn't much you can do. Disconnecting the O2 sensors will not help you any. I don't think you need new sensors...
