Ive had P0137 since the day I added my new O2 Sensors and RV6 PCD - Its low voltage on Bank 1 sensor 2 I assume hopefully the new O2 sensor that was installed isnt working and its causing the car to run rich?

I have been getting HORRIFIC MPG 270-295 miles on a full tank of gas.. this RL only gets Vpower Shell.

Im hoping this is the O2 sensor being bad but im filling up pretty fast now its getting expensive

 

I think you might need a spacer for the O2 sensor. I think it's called a defouler? Essentially the engine thinks the cat isn't working right and is adjusting. Technically the cat isn't working since it's not really there haha

 

this looks like exactly what I need.. I have another O2 sensor i was given for free since i told them the original was defected.. gonna get me an angled one and report back

 

Is this what im looking for? One of these 2?

 

I believe that's what it is

 

Didn't you buy your PCDs new? They're suppose to come with defoulers..
