PROBLEM SOLVED

Thanks Bob for the gaskets. Isuzu sent me a pair that also arrived today. We have the market cornered. Yours will be back in the mail tomorrow. Many thanks. If I can ever be of service to you or the group, let me know.

As to the solution to my idle problem--
The EGR valve sits on an aluminum block which is attached in two places: A metal vacuum tube coming from the back of the intake plenum and a flat metal bracket which bolts to the S/C intake manifold. A 1 1/8" spacer is between the bracket and the manifold. A bolt goes down the center of the spacer.
The bolt hole in the intake manifold goes clear through into the air path.
So, if the bolt falls up (!) and out of the bracket you have a 1/8" air leak and everything looks fine. My searching with starter fluid spray produced inconsistant results since I was squirting in the wrong places. I pulled off the EGR and replaced the gasket. When putting the valve back on, the spacer fell over. A search for it's home revealed the hole.

Since I have the appointment with the dealer all set up, I will get the 1441 code fixed finally.

Thanks for the support.
