Hello. Mileage is 83.3k, 4-cyl v-tech, 5-sp stick. No repair history, first real problem. Two weeks ago I was getting 42 mpg, now I'm driving a bucking bronco that's sucking gas. I have been diagnosed with a bad oxygen sensor. I'm sceptical. Had the plugs, cap and rotor replaced and nothing has changed. Quoted $650 for repair of oxygen sensor, seems high.
Are there any other options? Is the vehicle going to die on me on the road? Can I repair this myself? Would an air filter change help for the short term?
When we had a lot of rain last week things improved and the engine light turned off.
Thank you all for your help.
