I am in need of a rear O2 sensor. I know that this sensor isnt a vital part of the emissions system. However has anyone on here been succesfull using a resisitor, or a O2 simulator? If so which one. I need the Cel to go away for emissions. Thanks in advance for everyones input.

 

Even if the CEL goes away you'll still have the code in your ECU so if they scan your codes they'll still pull a code and you'll fail anyway (unless you're from a small town like me where they look the car over for 5 minutes and give me a sticker)
