First time Bronco owner

[Whitetail Trophy Chaser]

I've replaced the oil, air, breather and fuel filters; changed the oil and flushed the radiator. What should I do next? It runs fine when it starts, then sputters and dies. Once it warms up, it will idle for what seems forever, but as you shift into gear it sometimes dies. Sometimes will run and drive ok, then dies when I come to a stop. Gonna run Sea Foam through it and see if that helps, then start with PCV valve if it doesn't improve. Any other ideas of what to do?

What year is it? Is it carb or fuel injection? I'd replace plugs, wires,cap, and rotor. Check timing also.

Try tapping on the IAC (Idle air control valve) with a screwdriver handle or a really light hammer. If it is sticking, usually that will free it up temporarily.
