1999 chrysler sebring convertible JXI

car will start and run until it warms up then it boggs and dies when you acclerate.It died going 65 mph as well. The check engine light only came on when I removed the oxygen sensor then put it back in. So I had the car tested at parts store. They said it was the throttle position sensor. On the way home the light went out. The next day I replaced the sensor and it didnt work. What do I do next?
