I have a bad o2 sensor and i need to get a new one? how do i get to it and when i a website offers a universal type for so much cheaper why does it look different? could someone please help out a novice and tell me what o2 sensor i need for a 94 mustang v6

 

go to your auto parts store and ask them

 

autozone. i think a bosche universal for my car is $40 each

 

Often times the inexpensive/universal ones will have just a wire lead coming out without the connecter, and you are expected to cut off the old one and splice it back on. I don't know about differences in accuracy/reading though.

 

the bosche ones are direct replacement

 

I don't trust Bosh sensors.. Honestly I would go to the dealer and get them or get one from somewhere that offers motorcraft parts. universal is never a good idea. even OEM replament ones that are a direct fit can cause issues. I would highly recomend paying the extra and getting them from motorcraft.

 

why

 

I have seen issues with them. Once on a caddy. once on a dodge truck, once on a jeep and once on an f150. By scoping the 02 I knew it was bad. got bosch sensors. a short time later the cars all came back with the same codes. After several tests I could only come up with the 02 was faulty (try explaining a brand new 02 sensor being faulty to your boss). But I threw a delco on the caddy jeep and dodge and a motorcraft on the F150... After that all was good.
