MT,

There are numerous vacuum diagrams for ‘78~’79 posted in this forum that people had been using. It would be helpful to post some pictures for references during discussions. One good example is that front of the engine could be the rear or vice versa. When I look at the engine orientation after opening the engine lid, I refer to the section closer to the rear bumper as the front side others call it differently.

My next question just to be clear we are on the same page, which is the front side of the throttle body in your car (911)? The section closer to the rear or front bumper? Thanks.

Tony
