iv heard mustang owners when they run true duals or custom exhaust they eliminate the o2 sensors and they plug in some sort or connection which reads a constant..... do they make these for our rangers?



thanks.

 

What you are probably talking about is rear o2 simulators. They use them when they remove the cats so they don't get a check engine light. I'm not sure if they make them for Rangers but trust me you don't need them. Our engine don't move enough air to run without cats so taking them off will not gain you any power and may reduce low end power.

 

well now u see what my problem is the idiot i bought my truck from stock cut off the last cat long with the last o2 sensor so sense then i welded onto that and ran 45's out the back but i ran with out the last o2 for a while and its always stayed on closed loop and i always ran 19-20 mpg average....now its stayin on open loop and im gettin som seriously ****ty mileage.... any ideas? maybe weld in a o2 port?

 

Ah. I thought you were looking for performance. Well the last sensor monitors the efficiency of the cats. The only way to turn the light off is to install the sensor again or to get that simulator. I would personally install the sensor again. As far as staying in open loop that may be caused by something else but I'm not 100% sure. I'm assuming you got the code read? If not go ahead and do that.

 

alright ill throw the scanner on tommorow at work ......
