Has anybody done this on their own? What is the approximate cost and how long does it take? Also, where are they located?

Thanks.

If I'm correct, you have to removed the upper intake manifold and fuel rail. Not sure on cost as I've never attempted it. Seems to me, too much labor time. Get a bottle of STP Fuel Injector Cleaner for the next couple of fill-ups at the gas station. If your fuel injectors are dirty, you'll notice improvement. If you're not sure they are working properly, crank the engine and open the hood. Take a (preferably) pointed piece of wood with a flat end on the other. Touch it over each fuel injector and stick the other end to where it closes off the lowerpart of the ear. Sounds stupid, but it acts as a stethoscope. You can hear a lot of noises you wouldn't normally notice that way.

Does anyone have a picture of the manifold that comes of and the injectors (sorry, not familiar with things under the hood yet!)

this is a fuel rail from a 4 cylinder.... i couldnt find one off a v6. but they look similar. except you'll have 3 injectors on one side of the engine, and 3 on the other. (kinda like spark plugs).

no idea how to remove it from a v6... 4 bangers are alot easier to work with

On the V6, the fuel rails are sitting under the upper intake manifold (has the 3400 raised on top). If you look through the spaces you can see the two fuel rails beneath it.
