Check engine light

I Have a 97 TJ 2.5 and recently it has been having some issues. The check engine light came on and I ran the codes and it was a failed upstream O2 sensor, so I replaced it and everything seamed fine. The engine lift came on again and it was really sluggish and got terrible gas mileage. I researched it and everything I read about lead to the tps sensor, so I replaced it and it's been running better but the light will still come on and shifting at higher Roma it's a little hesitant. Can anyone help or give me some ideas?

Did you clear all codes?

I only disconnected it from the battery. The light went off and then when I drove it for about 5 miles that's when it came on again.
