Im throwing code 41 which is the 41 Primary oxygen sensor heater .. does anyone know if that affects your gas milage .. please help im going to fix the problem but i really i want to know if it gives u shitty gas milage thanks

 

yes,it will affect it.the ECU is probably running in a safe mode since it isn't getting a correct reading from the O2.this results in a very rich air/fuel mixture.
before you replace the sensor,check the wiring-i've often seen O2 sensors be bad and not throw a code,every time i've sen that code it's because the sensor is unplugged or there is a break in the wiring somewhere.

if your o2 is bad yes you will get bad gas millage. mine was bad for a couple weeks till i got a new one and its noticable.
