So I have a 1994 cherokee 6cyl manual and I need to fix its vacuum issues. Currently it idles around 800-1000 rpm and stalls out after engine braking. Is it possible to completely delete everything vacuum wise except essential things? I have the CCV completely disabled at the moment and want to make sure thats not a necessary system for the jeep to run right. Ialso blocked all HVAC vacuum lines. I need a good way to find a leak in the lines i still have connected that doesn't involve blindly spraying ether around my engine bay.

Edit: I also do not have a CAD system

 

Don't use ether. Use carb cleaner. It pinpoints vacuum leaks way better.
Here's a vacuum diagram.

 

I'm not willing to use any aerosol cans to find the leaks I can never seem to find them cause i don't have an ear good enough to catch the change in rpms. And starting fluid and brake cleaner are essentially the same when put into the intake to me. Neither are really supposed to be there.

 

And thanks for the diagram! Much clearer than anything on google images
