My question is what would cause o2 sensors to go out after they are replaced with new ones

What is your question?

I have an 2006 Hyundai Tuscan. My check engine light came on, had it tested and the test said it was o2 sensors were out. I had new ones replaced and the check engine kept coming back on with same code. What else could be causing this to happen. Could it possibly be the sensoŕ plugs going bad or what. No noises just makes vehicle run funny, like taking off it gets to 30 mph and kinda sits there before it will go faster, eats alot of gas. All maintenance is current so no leaks.

What makes this problem better or worse?

When new sensor is put in check engine light comes on the next day with same code

How long has your 2006 Hyundai Tucson had this problem?

About a month
