Thanks for the help. I sincerely appreciate it. I will check that out later today.
I did already check the vacuum source under the hood, where it connects to the manifold and then into the Y-connector located in that thick wire loom. I know the vacuum is still good up to that point. I will have to check the line that actually passes through the firewall and connects to that single lead hose located at that cluster of hoses on the programmer.
Thanks again. Wish me luck... It'* so hard to get to with a bad back!
