Evidently last summer when I had the Trilogy off I managed to knock something loose in the vacuum from under the hood to the eatc module.
I thought maybe it was coincidental that the O rings might have failed while the car was apart so I did the O ring fix, they were bat but not the problem.
I just pullet the eatc module out and started the car and there is no vacuum there at all.
the vacuum canister under the hood has vacuum but behind the trilogy where it all goes in I can't see, I tried getting in there with my stethoscope buc couldn't hear an air leak.
I need pictures from NA/Centri guys of the area where the vacuum lines go through the firewall into the dash since I am going to have to fix it by braille (or pull my SC back off again).It would be a good to study 1st.

Just pull the wiper cowl and you will have all access to the firewall. 10 minutes is all.

Thanks Bob, I'll head there now.

I found a vacuum hose melted in half from under the car, it is the black hose, but I could only find one end, the end that goes through the firewall, I cheated behind the eatc and put vacuum in the black hose there and got correct operation. Now I gotta find the other 1/2, I'm thinking the chances of melting the hose in half and not causing a vacuum leak are pretty slim.
