My M5 runs better when it's cold...
I've been noticing that my M5 runs better when it is warming up. It seems to rev faster and be more responsive overall.

However, when the engine gets warm, it seems to "fall off" a bit. It doesn't run bad or anything, it just doesn't seem as responsive as when it is warming to operating temperature.

Has anyone else had similar a problem?

I plan on replacing the oxygen sensor as well as the engine temp sensor. Is there anything else I should look into replacing or any advice on this?

Thanks!

All correct steps. You might also search for air leaks.
