How to replace wheelbarrow on ford expedition 2001

SOURCE: 2001 ford expedition spark plug location

That's because they are hidden quite well. If you look at the engine, you'll see yellow plastic prongs (?) that look like spark plugs, but hook up to the silver tubing.  That's the fuel injectors.  BUT, right behind the yellow plugs, are black ones.  The black one is the connector to the spark plug.  The plug itself sits about 4 inches down into the block of the engine.  They are a real pain, and from what I can tell, you only have decent access to the first 2-4 of them, then they get too far back and start going under the dash (you'll see what I mean when you get there).
