I have a 1993 Chevy Lumina APV that is missing a vaccuum hose coming from the throttle body. I have no idea where this goes, but I think it is the reason for the problems I have been having with the vehicle shutting off. Can anyone tell me where the vaccuum lines from the throttle body attach to?

if the battery was disconnected then you need a idle learn done at dealer if not the you have a vacuum leak listen for a whistle when started and try to pin point it
SOURCE: what two coolant lines connect to the throttle body on a 3.1 multi port engine
There are no coolant lines connected to the throttle body, just the two fuel line. The high pressure side and low pressure side (Return line) and I believe the lines don't even connect to the throttle body on a multi port engine, the lines go to the fuel rails to the injectors.
Good luck

On the 1989 s10 it has a vacuum actuator that actually locks the front differential in ,you need to check that first, those go bad real often,and without it. There's no way it will lock in the axle, the transfer case will lock in ,but the front differential uses a actuator. It 's located under the battery tray and there is a cable towards the front of the differential. Id say the actuator cable has gone out, most parts stores can get you one ,that what goes wrong with those 99% of the time and it only takes about 5 minutes to change it out. Good luck but check the vacuum line to the actuator under the battery tray.

Make sure you don not run low on transmission fluid in your transmission. Low transmission fluid will cost you a new transmission. You have the transmission line that connects to the upper passenger side or the radiator and the lower passenger side of the radiator. Determine which line has gone bad and you can buy a rubber transmission line hose at most Auto Parts store like Parts Source. Cut off out the section with a pipe cutter that has corroded through and replace with the transmission hose. Make sure you tell them it's a transmission line hose your looking for and don't use any other hose and double clamp with a compression clamps at ether end. If it's the connection at the radiator that has gone bad, replace that end and do that same as you would to sectioning off the the corroded line and try not to have more then 3 inches of repaired section. What ever you do, do not add any stop leak, this will create problems with the shift solenoids and check valves in your valve body in the transmission causing a transmission replacement soon after adding. Good luck and keep me posted.
