Actually I used to use 93 octane until gas rose, but I probably need to start back up. I just got a code yesterday P130 (front right O2 sensor).

MAY THIS BE THE PROBLEM!!!

Wouldn't a dying front O2 sensor effect the fuel/air mix ratio and cause the car to run as I stated initially...sluggish, hesitation & high odor emissions?
