my 1988 celica idles when cold and wont idle when warm.

First morning start. It starts up and idles well then when it begins to warm you can hear it want to cut out & die... eventually it does. But it will start right back up.
Here is another issue. I have 3 vacuum lines off two suck and one doesn't.
One of the vacuum lines are on the intake. The other one is below it and the last line is on a vac/ act I don't know what that is.
If anyone has any pointers it would be appreciated.

On the idle issue, you answered your own question... vacuum leak. At the very least, cap the leaks.

Yeah I'm sure the leaks are the issue.
Does anyone know where to find a good vac diagram?? Very detailed ..
