o2 sensors? need help? I have a 98z need two front sensors..how hard are they to change and with wich brand should i go.. from dealership? my car is prtty much stock?? any sggstions
Don't get them from a dealership, they'll probably rob you blind. Check your local parts store. They are pretty easy to replace as long as they aren't seized to the pipes. Pickup an O2 sensor socket for about $10 and it'll make the job much easier.
I need a new sensor and had it replaced when I changed the exhuast from Loud Mouth to GMMG's. I paid about $75 bucks for a new unit. Its a no-name brand but works fine. The old unit was caked up with carbon build up. It was tripping the check engine light. My car is heavily modified, heads, cam, intake, headers, etc.

The 02 Sensor sockets work great. Be careful of what kind you get. I have ran into some that the opening for the wire is way too wide and when applying alot of torque the socket will actually flex and slip off of the sensor.

Also check if your local parts store can get NTK/NGK. They work great, my car ran real rich for a long time , dropped a couple times and still switch great. The NTK number is 21544 and can usually get them for around $50
