Vacuum Diagram

[blessedguy]

Camoit,

I did unplug the hose from the pvc and it smooth out pretty good. I cleaned the pvc and put it back and all was good. Hopefully cleaning this EGR will work. I just got a gasket for it as there wasn't one there. Look at the 3rd picture in my previous post. Can you tell me where that vacuum line off the top of the carb goes? My is plugged/capped off.

Also, attached a full veiw of engine bay.

Thanks
