83 cj7 idle

I just bought a 83 cj7 with a rebuilt motor, recent Holley carb, etc. I drove it home (250 miles) and all was great. Two days later, now it idles really bad, and even dies at some intersections. The only thing I did was change the heater core. I assume I have a vacuum leak somewhere. Any ideas where to start, it does have the TFI upgrade. One more clue, if it dies, it seems to be able to fire right back up and idles fine for 10 seconds at about 1100 rpm then drops to 700 and gets rough all over again. Also, any suggestions on tune up, plug type,gap,timing, sorry so long. New and ready to go. oh yeah, in the morning I have to dance on the acclereator and pump like mad for it to start. After a rough warm up period it starts great the rest of the day?

I'm use to IH and Ford motors (pre smog) simple is grand
