Should I replace mine?
I see things that going into the exhaust manifolds that look like o2 sensors, but not too sure. I'm going to pep boys saturday and might as well pick them up. Mine Look like the originals.
This should increase my gas milage right? Cause , my car is getting about 15/g right now.

Well, if they are the originals and they are bad and you repalce them with new ones you should see some improvement. Don't expect it to magically jump up 10 MPG though. Did you finish all that other tune up stuff? From your previous posts it seems you've been quite busy. Also, as for as your driving is concerned, are you driving mainly stop & go or highway?

Stop and go.
I just replaced 4 spark plugs. What genious designed this engine compartment?! I could only get the center passenger side spark plug! The rest are not accessible with ordinary rachet wrenches.

there are no such thing as a "wratchet wrench" that works as a spark plug remover as a stand alone tool.

Ooops, I got the two confused because they both basicaly do the same thing. But I meant socket wrench, but I did use a ratchet wrench for the spark plug that's in the tight spot.

There realy is no such thing as "ordinary" tools and "unordinary" tools, there's just the right ones. If you have a couple of diff. size extenstions, and a knuckle joint to give your sockets a little angle you can get to all of the spark plugs pretty easily. You just need to be patient and if you need an additional exension or knuckle just go buy it. Make sure you have the O2 sensor socket before you try taking the O2 sensors off or you will prob. get frustrated again. Having the right tools makes a lot of difference even for the simple jobs. And oh by the way, all cars are going to have things about them that make you wonder what the engineers were thinking when they built it, its just a fact of life, like death and taxes. Good luck, Jason.

You GOTTA change those plugs. I'm sure that might help a bit too. My red '87 3.8 was a real pain in the behind to change the rearmost passenger side plug on. In fact I find it much easier to change plugs on my 5.0.
