Ok as the title says where is it located and can i change it myself? How much do o2 sensors run for? i want to avoid taking my car to the shop because i have no time to leave it at the shop. Mods feel free to place this in the right area.

$80!?! Where did you pick it up? I paid like $130 back in the day.

Oh and the change is easy. You can do it yourself in like 10 minutes.

does it even need it though? I was thinking of changing it before it did my new injectors and stuff but people unplug theres and its like nothing happend

Personally I hate the darn things. They wear out too often. Thankfully I will be running a WBO2 soon, and replacements are $40 (the one used on the LC-1 anyway).

Yes you need them. The ECU runs in open loop mode with a broken or disconnected O2 sensor.
