Time to take the old one off and put the new one on. Looks like 2 ways to do it. First is to remove the distributor so you can get to the bolts on the bottom of the intake manifold. second is to remove the throttle body so you can reach the bolts. Any suggestions? Is there yet another way?
Remove the distributer cap and 3 plug wires so you can swing the cap out of the way. Take your "not so good" 10 mm box wrench and put it in a vise. Start bending it to accommodate the angle you need to reach the bolts under the intake. Also take a wash cloth and stuff it down into the pockets where the bolts may fall and be gone forever.
I've done this enough times I should get a patent for the bent wrench.
Edit to mention the 10mm may be a 9mm. Check before bending...

I never would have thought of that. Excellent solution. Only problem is that I don't have a 10mm to spare (ought to be since the EGR end is 10mm). Only have one 10 mm wrench :-( I should be able to get a "bent" 10 mm at Autozone or some other tool place, though.
I just did a tube change an it was not hard to do if you remove the dis cap as spoon said, also take a rag an put it under the tube bolt's so if thay fall (an thay will most likely) you can slide the rag out to grab them. I also would put the left bolt back in first under the intake it's the hardest one to do. Put some heavy grease on it. It will help hold it in place so you can move you hand to spin it to git it started. Have a cold beer handy an take your time an just stay cool, an you'll be done before you know it. Good luck.
So, I have a new EGR tube installed. Thanks for the ideas. I ended up buying a ratcheting box end at Sears that lets you set the angle. It was $19.99 but worth the cost. The right hand bolt was the hardest to get out and needed a regular box end to break it loose first. Need to ask Santa ( or Mrs. Claus) to get me a whole set of those wrenches this Christmas.
I cut the cover off the corrugated tube and did not see any cracks or other holes, so I have a new pipe but likely did not fix the problem. So the guess is either the IAC sticking or the EGR is actually open.
Have to wait for tomorrow to replace the rotor that broke when I tried to remove it. Then I can diagnose more. Thing was rusted to the shaft!!! Never saw that much rust inside a distributor. This rotor and cap had to be on there for a decade or more.
It's always a good idea to take your upper intake off at least once, like previously stated, because you can look over all the plastic vacuum tubes and fix them if any one is plugged or cracked. Can't really observe them if the intake is on as its in the way.
