I haven't been on the site in a while (starting my own business is takin all my time) but I finally had my mechanic pull the CEL code for me and it was P0031 - Front oxygen (A/F) sensor heater circuit low input. I have the 1/2 watt resistor mod in place for the uppipe and the Pony Express MIL eliminator mod installed also. Any ideas as to why I'm still getting this CEL?
I'm getting COBB to reflash my ECU anyway, so it might not even matter, but I was wondering what could be causing this.
Any help is always appreciated. Thanks.
