Anyone know where I can purchase an 02 sensor for my 94 firebird formula? It is time for replacement...

How hard is it to install?
Anything to watch for when installing it?

 

you can get them from advance auto parts, autozone, most of the big parts stores have them. Not hard to install at all.

 

I would strongly suggest that you use only the stock, factory OEM AC/Delco O2 sensors for replacement. There are online sources that will sell them for close to 50% of dealer list + shipping. Do a "search" for "Jason Cromer" or "gmpartsdirect". You will need the part # if you try to order them from gmpartsdirect.com You can find the part #'s for many 4th Gen parts on Shoebox's Tech Pages.

 

The stock ones may be pretty frozen(rusted) in your exhuast manifolds. Get some PB Blaster and soak the threads down good to make removal easier. Then put a little anti-sieze on the new ones to make future replacement easier as well.

 

Thanks for the info Injuneer...any reason that the AC/Delco's are better for our cars?
