My car stall out while driving. The mechanic said it was the O2 sensors after hooking it up to the diagnostic machine. Would this cause the car to stall out? It stalled out while on the highway one day, which concerns me?

Yes if the heater sorts to the sensing element they can cause the engine to stall here is a guide that can walk you throught he steps and the sensor location and instructions on how to replace net in the diagrams below.https://www.mslsec.com/articles/how-to-replace-an-oxygen-sensorCheck out the diagrams (Below). Please let us know what happens.
There is some conflicting info there. Your getting codes for both rich and leans condition so if you are correct about the code numbers, then you likely started with a severe rich condition that eventually clogged the O/2 sensors to the point they can only read lean.At this point you probably have ruined the O/2 sensors due to driving it too long with a rich condition. Your going to have to start with new O/2 sensors and then look for the original problem. Clear the codes after the sensors are replaced and then see what codes reset after replacing the sensors. Then you”ll get an accurate picture of what may be the root cause of the problem.
This is going to be a three hundred dollar expense unless you do it yourself. The sensors can be replaced is less than an hour.
I have a 2005 Ford Expedition. My check engine light has been on for almost a year now. The code it throws is the O2 sensor, bank 2. I have had the sensor replaced 3 times. I've also had the spark plugs and coils replaced. Light is still on. Trucks performance is decreasing. Exhaust recently started smelling bad. Truck will shake at idle and sounds like its going to cut out. My friend (who is an airplane mechanic, but also knows a great deal about cars) said he thinks it's the cat converter. He's never looked at my truck but feels that's what it is. I've brought my truck into two different places, one being a Meineke, and they both said that the “code” says its the O2 sensor and that as far as they could tell, the cat was fine. WELL. CLEARLY SOMETHING IS CAUSING THE O2 SENSOR TO CONTINUE TO FAIL! Any ideas. Please help!
