4.0 idle drops, stalls sometimes

[B30004X4]

I have a 97 4.0 that has a problem after the vehicle has reached operating temperature. The idle drops and it will stall occasionally. When i notice the rpms go down i keep my foot near the gas in case it wants to stall. I have replaced the dpfe sensor,idle air control, and cleaned the mass airflow sensor. Im thinking it is the egr or the egr solinoid. Anyone know anything about this?

the only thing i can say is you probaly have an air leak some where and they are hard to find to me .
