O2 sensor cure PING?

Yes. The O2 sensors are a problem and need to be replaced. They are a time change item designed to last for 30,000 to 50,000 miles.

What's more important is the overall condition of the rest of the engine. Putting brand new O2 sensors into an engine with a lean condition will effectively 'wipe out' those brand new sensors.

While it is true that a malfunctioning O2 sensor can cause an engine to run poorly; It is also true that a poorly running engine will kill an O2 sensor.

What I mean by all of that is that "yes", you need to change the sensors but changing them is not likely root of your issues. I would also be looking very hard for bad gaskets and hoses. Anything that might lend itself to a vacuum leak.





Though not shown as a category in the above line-up, I would say that yours fall into the "Completely Toast" column.

I keep forgetting you have a 4cyl, that idle is kinda high I would think. Most cars idle around 650-750
