Ford Repair: Ford Bronco 4x4, vacuum hoses, ford bronco

Question
My truck will not idle right. Running fine one day and the very next morning it was messed up. I have changed the plugs and wires and it helped a little. It will now idle but sounds like it could shut off anytime. Very annoying when sitting in traffic. Had the carberator checked and was told it was fine. Any suggestions on what to do next?

Answer
I would check the carburetor chock assembly, it might be getting stock while idelling.  Also, check all vacuum hoses and insure that they're not cracking and/or leaking.  Additionally, clean the moving parts with carburetor cleaner.  Let me know if this works, otherwise we'll try more involve options.
