Changing plug wires, 92 E-150, 5.8 litre
Is there any way to change the plug wires on the passenger side, without removing the throttle body? I changed the four wires on the drivers side, and finally gave up on the other side. I now have four new wires, and four old wires. Runs OK, but I hate to do anything half assed.

capstan,
You need to remove a few things to get the job done. After that, it's pretty easy.
First, remove the air cleaner box and the two large rubber air intake tubes and any related hardware from the front.
Next remove the dog house engine cover from the rear and look at the rear passenger side of the engine where you will find two rubber hoses, a vacum controlled valve and a vacum line that comprise the aux. air injection system. They wrap around the right side of the engine and are held to it by a bracket secured with two fasteners. I can't recall if one is a bolt and the other is a stud and nut, but whatever, remove the two fasteners and free up the hoses. You will also need to disconnect the vacum hose to get free motion in the larger hoses. Don't remove the larger hoses, just move them out of the way.
Now, place a shop light at about the point where you removed the fasteners and return to the front of the van and feed the new wires, one at a time, through the path that the old wires are running. You will be able to see through there with the light so positioned. Now is the time to replace the plugs too. Just moveing thoose air injection hoses up a few inches makes this job way easier than on any late model pick up. I believe we van guys have the advantage on that job compared to the modern PU.
Give it a try, it's not too bad once you move a few things. It takes a little patience to get the two fasteners off but it's the only way to go.
Also, check for vacum leaks, hose chaffing and deteriorated rubber hoses as well as checking the fuel pressure regulator and taking a fuel pressure reading while your in the dog house. It will just take a few more minutes and will save having to open it up again later.
