Running rich and sputtering at idle

Dash lit up on my 2000 SLE and I had misfire and o2 sensor codes coming up. I changed the o2 sensor and spark plugs. Car ran great for 140m. Now it's sputtering at idle and running super rich. Could the o2 sensor I bought be bad?

we had sputtering at idle and it was EGR valve. They can just clean it for almost next to nothing and it should fix the issue.
