I already know that I have a faulty O2 sensor, the one after the cat. The shop that I get all of my work done at has an Escort (late 90's) that the engine is blown. My question is will the O2 sensor from that car fit on mine assuming that it was not damaged during whatever cause the Escort's engine to blow? Hopefully so because they said they would swap it for free if it works. BTW, I drive a 99 SE. Thanks in advance.
