Rough Idle on warm start

My 86 22RE runs great but when I start the vehicle after it's warmed up it runs rough for about 30 seconds to a minute and sounds like it will stall. If I rev the engine it will clear up a bit but goes right back to a rough idle unless I put it in gear and go. There are no problems with a cold start.

I checked for trouble codes and got nothing and all of the usual maintenance items have been replaced or checked.

Any ideas?
