        3 2014 V6 - Weekender

        don't know yet

        Replaced stock 02's last summer with these, upgraded to long tubes and an off road x pipe summer before that. The car is stored for the winter so it didn't really run much after that couple thousand miles at most. I got it out this spring and put maybe a thousand miles on, and I am already getting bank one o2 sensor codes. I have to think I have a harness problem so its probably not the new sensor's causing the problem, so my frustration level is about as enthusiastic as interest a person has over last years bird nest I should have replaced the harness's as well. The fitment is perfect, they plug and play with no splicing which is great in my opinion so changing them out is a breeze even with ramps or jack stands. I am going to give them one more shot including harness's this time if I have another problem next spring maybe I will just give up and buy a hybrid.

        I was having issues where I was getting “Lean” codes. These did the trick. Not on;y did my code issues go away, but I have gained about 2 mpg over the last couple fill ups.

      I want to replace my o2 sensors but how many do I need to change them all I think I just have 2 My car is a 2012 mustang with bbk headers and x pipe roush mufflers air raid cold air intake bbk throttle body and bama tune but the car has a little bit of a hesitance at idle but runs fine when I'm going so I think the o2 sensors might be bad or burnt from the free flowing exhaust my car has 27000 miles and spark plugs look great no engine light

      • Its possible. Oxygen sensors get a lot of extra airflow to them with longtubes. If ita not throwing a cel tho I'd look into non-foulers.

      I have 2013 gt. I put the factory cats back on for inspection but the monitors wont ciear for cats 02 senser and 02heater it doesn't show codes is it possible to have a bad senser

      • The emissions monitors will require you to complete an emissions readiness monitor drive cycle for all monitors to run. Additionally if you have an aftermarket tune this may cause the rear o2 sensors to be deleted or modified. If you have completed a drive cycle and the monitors have not set, we recommend consulting with your tuner to see if O2 sensor parameters have been modified.

      I have to replace Bank 1 Sensor 2. Is this the correct sensor and is Bank 1 Sensor 2 on the driver or passenger side?

      • Yes, this is the correct sensor for the rear O2 sensor, and bank 1 is on the passenger side.
