i should add, plug all the open tubes with golf tees, and see if it helps with the non functioning doors etc.

Has linkage from the throttle going over the valve cover to the right side under the manifolds back to the trans on the right side. It shifts fine through the gears. The vacuum pump is sucking but it doesn't feel very strong. I'll get a reading on it tomorrow to see what it's pulling. The engine also shuts off right away so that part seems to be working fine.

The other side has another 1 to two hose valve with a green line and a red/white line. There are two yellow lines coming out of the firewall into a three way fitting that has the third part plugged.

I have 3 hoses that were plugged off and need to find out where they are supposed to go. I think one or more might need to go to something on the valve cover but nothing up there. A diagram for a 79 would be good, also. I find a lot of diagrams for newer models, but they all have an EGR and mine doesn't.
