Hello everyone,
Just bought a Comanche recently and it pretty much needs tons of work; currently in the process of repairing the infamous Flintstones Floor panel.
The engine is where I need help with; as of now I have not been able to locate a good vacuum diagram to work with. My 4.0 starts and runs OK but there is a vacuum hose on the intake manifold that is disconnected; but when I plug it back on the engine RPM drops and it runs real rough for a few minutes then eventually, it shuts down.
Also, please let me know what's the broken vacuum hose locate on the passenger of the firewall use for? the rest of the piece is nowhere to be found so I have no idea.
Thanks in advance for all your input.
Van
