I am attempting to fix a rough idle, that often dies if put into gear before it is up to temp on my 1980 J with a 360.
What I found was the previous owner butchered the vac systems, The CTO valve on the thermostat housing has three ports with no hoses to be found and according to the manual that controls my timing advance when cold/ hot. I have a feeling it might help keep my idle up when shifting into drive or reverse.
I will worry about the other vacuum/evap stuff as I come to it but I want to start off simple and work my way into the rest of the system. I still have to come up with a reliable evap delete since the canister and all hoses are missing as well which I need to remedy at some point to keep the fuel consumption down.
I am hoping someone has a picture that would help but some routing details would work too. I have been going over the repair manual and it has great information if I were looking at a vehicle right from the factory, but it doesn't help me when most of the items described are missing. I am not even sure what the distributor is hooked up to at the moment.
