Prosport wideband issues.

I am having a problem! My wide-band gauge reads 20 lean most of the time, it will change if I rev the car but then goes back to 20 at idle. This sensor is pretty new I replaced one already.

I have it wired to the ecu and Ecmlink tells me the wide-band is at 9.6?? I can smell gas from my exhaust, I just have a hard time believing that the sensor is bad already.

I also had a problem with an brand new o2 sensor reading 2.56v during idle... I have the wide-band in the stock location now doing 02 narrow-band simulation and there is no change, I tried to recalibrate the sensor but no luck.

Could I have wired the narrow-band simulation wrong? or am I out another 90$? No kidding the sensor has seen probably 300 miles over the last 6 months.

I don't understand why it reads lean on the gauge but in Ecmlink it reads rich?

Any help would be great guys.

I think I may have figured it out. The wide-band will respond but not at idle, I am guessing it has something to do with the large boost leak I found in the injector lower seal.
