    Hey Gearheads! Need some help!

    Ok, not that kinda gear you knuckleheads!!!

    I mean guys who wrench on cars!

    Ok heres my question...

    I need to get a smog check. I took my car in for a check and it failed the function test. The cause was from the check engine light being on.

    So i have a diagnostic run, and it comes back that the O2 sensors are getting readings.

    Well my car (2000GT Mustang. Thats a 4.6L) has four. And all four sensors are getting bad readings.

    So now my choice is to let this mechanic replace them all for 400 bucks. Or i can pay 41 bucks a piece for a sensor and replace them myself.

    I have a tourqe wrench and im currently looking for the specialized socket for the sensor.

    So basically my question is has anyone had experience with this before?

    Im not used to working on newer cars, i usually work on 1st and 2nd generation Chevys. SBC's and a few pontiacs...

    From the looks of it, it seems to be an easy job, but anything i might encounter would be nice.

    I know about the possible seize, hopefully thats not gonna be a factor but who knows?

    o2 sensors should be done every 100,000 klms. Most cars only have one, its an easy job, never worked on that model but sometimes they can be in awkard spots. Good luck

    a 21ml open ended and a torch

    they will most likely be seized/fused with the exhaust - you'll need to heat em up a bit to remove em.

    loosen a hair, re tighten, loosen a bit, retighten, then they'll come free.

    i did it just last week on my 1999 honda civic winter beater...

    304,xxx km's on it, and it still RUINS etests and i get 600k to a 40L tank

    Do it yourself and save some bucks. I got a 1996 **-7 and I've had to replace the O2 sensors. It can be a pain in the ass, but it's not that hard. You can probably download the instructions for your car from somewhere. GOOD LUCK!!

    Good man you know what your talking about at least. They will need to be heated to get them out as from all the Mileage they will have seized in there. Not a hard job really just need a bitta paitence and a lift would help but a decent jack and axle stands will suffice.

    hook the computer up to a tuner, cancel the rear 2...the front 2 are easily replaced...or just cancel all the codes and youll pass inspection.

    actually...just sell the mustang and buy a trans am!

    ^^ Please, if anything id buy my 69' Camaro back...


    I already had the codes cleared. The problem is that the check engine light clicks on and off periodically.

    So the sensors have to be changed.

    Theres four sensors total. Two under the intake. And two attached to a relay under the exhaust.

    They only require two. Im thinking the front two are more signifigant and i should just replace those.

    I know where they are, its not gonna be that big a deal. I was just curious if anyone had tips.
