I tried to take my o2 sensor out yesterday and ran my car. It richened itself but i didnt try driving with that because i didnt think it was a good idea. Does that mean it was my o2? I tried searching for leaks with carb cleaner and i sprayed it at my hoses like vaccum hoses and all my turbo hoses ect. Idle didnt got up.
