I have a 2000 toyota 4runner with 126000 miles. It idles rough. The mechanic told me to replace the oxygen sensor to the number one cylinder. Does this make sence?

Yes it does, but first scan it for trouble codes, that way were not just guessing various things can give it a rough idle, such as a bad IAC.
