i just bought a new o2 sensor and i need help installing it on a 240sx help please anyone with experience
What do you need help with? Use a 7/8" wrench and pull the old one out. I have an 02 sensor tool, if you are local I might be able to help. Sorry, just noticed ur in cowtown, lol.
how did it turn out ??? should just have an electrical plug on it and then just take a wrench and take it out, put new one in, probly a lil anti-seize on the threads and torque it on, plug it in and your good to go, if it doesnt have the same plug make sure it has the same number of wires not sure how they all work but there are different types 1,2,and 3 wire systems i know for sure. 1 wire systems just have the 1 wire that runs to the ECU and doesnt need any power source ??? not sure about 2 wire systems 2nd is a ground ???/ and then 3 wire o2 sensors will have a ignition, ground and signal wire
