alright. I'm completely noob with fixing cars so don't make fun of me. My front right O2 sensor needs to b changed. first where can i order this part? for my 00 eclipse gt cali spec version. and next is this hard to DYI? and if it isn't how do i replace them thanks guys.

Just get a new o2 sensor from the dealer. How hard is that?

Autozone can get them for you to.

its a easy job make sure you get a o2 socket to remove and install,or a 22mm combo wrench if you can get it to fit.but make sure you disconnect your 02 sensor first

O2 sensor sockets you can "rent" from auto zone. you give them the money it would cost to buy it, use it, then once you bring it back the refund all of your money. its a lot better than having to buy a O2 sensor socket.

owning a O2 sensor socket when you are not a shop mechanic, is kind of like the kicking someone in their balls fight move. you have it, its there for you to use, but you only get to properly use it once in every 5-7 years.

Make sure you use anti seize

you might not need an o2 sensor wrench, just a 22mm wrench will work in some places

heres a site where you can order one. make sure you match the model numbers with your old one and when ordering a new one
