Check your throttle cable spring, might be sticking a little bit, also could be a tps issue but normally that also causes rough idle with the rpms surging up and down at idle. Could also try cleaning your idle air control valve to see if that helps any.

This manifold sits under the fender on an '85 carbureted GT rag top. A forever project replacing many vacuum lines destroyed during a flash fire under the hood.
Vacuum line goes through the fender wall, I have not yet identified the terminal end. What is it and what does it do?
