p1133 with stock car my ses light is on and when i scan it this code somes up. I have searched on it in this forum, found a lot of info on long tube headers how they dont work but i have stock manifolds, does this mean that my actual O2 sensors are bad or that i need to tune them out, car is a 2000 z28 stock.
thanks

P1133 is Insufficient Switching bank 1, sensor 1 (drivers side precat sensor). Could be an exhaust leak near the sensor, wiring, corroded connector, etc. You can look up the diagnostics at gearchatter.com for your year. Don't want to tune it out - you need the precat sensors. Probably just a bad sensor it the code keeps coming back.
