I'm throwing the heater core, blah blah code for the rear o2 again but cannot afford to fix it. Could this lean/richen anything or make my car run funny? Is this something I can drive with? I know guys delete them, but I don't know if they have to get a tune or something. I'm worried because I can't replace it right now but I need to drive my car.

Should be covered under the emission control equipment warranty - give the dealer a call.

Jaemon52

Yup, just called them. ******** said it's not under warranty and would be 235 with labor. Theifs.

so will I have any issues without it for a while?

Should run not to bad as long as your not punching it .If you drive normal I dont think it will kill the car.
The car will run in closed loop but might be a little rich,meaning it could be bad for the cat.

Jaemon52

Wait, so you're saying the rear o2 does more than just make sure the cats not killing the environment? It actually determines afr?? ****

Coblasts

No but when a sensor is not working the car automatically goes into a closed loop.
It then runs on preset tables which generally tend to be on the rich side.

Just found out the bosch o2's have a different heater core design and can trip CELs with our cars...****, looks like I'll have to drop 90 bucks on an acdelco

if you still have a cat on your car and your throwing a code for the rear o2 sensor there is a good chance ur cat is getting clogged.
