2001 Saturn SL1 throttle position sensor question

How hard is it to replace the throttle position sensor and "heated" oxygen sensor on a 2001 Saturn SL1?

I know that it is relative to my abilities. I have in the past replaced alternators, starters, water pumps and things of that nature.

Any help would be much appreciated.

i doubt these two will be out of your abilty. the rear O2 may be a pain because of a heat sheild in your way. the TPS i beleave will require removing the throttle body, so buy the $5 gasket and you are all set.
