Guess it's a good thing i found our o2 sensors for less then $100 on amazon lol....one last question though, would the throttle response get worse as the o2 sensors heated up even more, like say as oil temps moved beyond 200 degrees or an extra load was put on the engine like ac being turned on?

Only way to know that is to have someone reading the scanner as you drive, or have a way to data log the information.
