You can find a vacuum diagram, for your 1992 Ford F1 50 pickup truck, at most Ford dealerships. You can also find the diagram at most auto-parts stores.
No the 390 is a big block the 302 is a small block.
The vacuum diagram can be found in a service manual. Your local library may have a copy of the manual that you can check out or copy the diagram from.
Need more information.
probably a bad idle air controller.
The vacuum at idle should be a steady reading between 17 and 22 inches ( in-Hg). for most automotive engines
The EGR valve on a 1979 F150 with a 302 is located in the center of the engine. It is close to the firewall.
You can find a 1987 Ford E1 50 vacuum operated heater control diagram at your local Ford dealership. Most local libraries will have Ford service manuals with the diagram.
Check in the chilton manual, if u do not have one, the main library usually carries them.
