Follow the master cylender (back of engine compartment in front of steering wheel) vacume (black hose 1/2 diameter) about a foot to your left as you are looking into engine from the front. it will stop at a multi port connection (directly abouve the last spark plug on the right of your engine) There should be (least on mine) seven vacume connections. Two inches to the left of the wiper motor. Hope this helps you

 

Got your e-mail today, this morning, thought I replied but see that I didn't.

OK this vacume port is located at the back wall of your engine compartment, two inches below and to the left of your windshield wiper motor, or about a foot to the left of your master cylender (which is the big round thing on the rear engine wall) follow the 1/2inch hose from it to the vacume I was talking about. There should be about 7 little hook-up points there, most just contain a cap, no line to anywhere else

Again, sorry for the delayed answer

 

I checked all of the ports and each one had a cap ont it and it was secured tight. Do you have any more suggestions?
