Need some help on heated o2 sensor
Don't know but I've been told my problem with my car is my O2 isn't working correctly ...Car will run fine for awhile then it starts running rough,will backfire when you floor it.
I've done most all the things that I've read on here and finally decided to do the heated o2.Picked the bosch unit up from Advance auto...13190 was the number I'm pretty sure but now I need to know where to put the wires.
any help appreciated

Re: Need some help on heated o2 sensor (JOliver)
Two of the wires will be the same, one will be different. The different one is most likely purple, this is your signal wire. Connect it where your existing O2 is connected. The other two wires are power and ground. Since this is simply a resistor style heater polarity doesn't matter. Connect one wire to a switched 12v source and the other to ground.
