I'm currently in the process of replacing all the vacuum hoses on my '76, but all the vacuum diagrams I can find are at least slightly off or miss stuff. Mine is a CA model with all the goodies (EGR, air pump, catalytic converter). Does anyone have a suitable vacuum diagram?

One thing I noticed is that the EGR valve is not connected to anything and I cannot find an open nipple for its vacuum line, which is still connected to the EGR valve, on the throttle body. However, the distributor advance is connected to a nipple in the correct vicinity, which, according to one diagram I have, is simply not connected on many 74+ cars.

My symptoms right now are that the car wants to die badly when started and hesitates/bucks when I'm not careful during warmup.

Any help greatly appreciated (IMG:style_emoticons/default/smile.gif)

take some pics of the engine and smog stuff. I have never seen in person a complete setup as its usually been hacked or removed.

The vacuum advance should be going to no where. The vac retard is what should be hooked up. This is the lower slightly larger hose on the vac can.

I'll try to take some pictures tonight if I don't forget it. The setup is indeed complete (I bought the car less than a month ago and it had 24,500 miles then), but might have been in the hands of less-than-competent mechanics.

The vacuum retard is hooked up, that one winds around to the opposite side of the throttle body.
