What year T-Bird.
This could be as simple a vacuum leak from a hose that didn't get connected or was broken during the install. It could also be bad timing, bad plugs, wires, etc.

Did the installed put new spark plugs, fuel filter, PCV valve and plug wires (if so equipped)?

Also be sure the plug wires are connected properly according to the firing order.
