Bad vacuum lines? - Third Generation F-Body Message Boards

Hey guys, I was looking under the hood of my car and I noticed this:

From what I understand (correct me if I'm wrong) those are the vacuum lines. And they look pretty old and cracked. Do you think that they may be (at least partly) responsible for my rough idle and difficult warm restarts? And is this DIY job? I personally don't see why not.

Oh and the car is a 91 T/A with the 305 TPI engine with 98,000 miles.

you can buy vacuum tube from any parts store and replace them and they could very well cause a rough idle I'm not sure about the warm up , little tip do them one at a time pull one off and put the new one right on so they all get back together right it's not hard at all good luck hope that fixes you problems.

One of the old tricks I've used on cracked & suspect vacuum lines (on boats) is "Liquid Electrical Tape". Just paste some on the crack. Run the engine for a half minute. Shut it down for 10 mins (allowing the L.E.T to dry) and away you go. It's not a permanent fix though..... There's also a "self healing" rescue tape I've seen used but never had any myself.
