it could be your idel air control valve.i have a 97 sohc 4.0 and it made a loud horn like sound.i replaced the valve and it fixed the problem.

Yes i think that may be it that was my Second guess at it i still want to replace the PCV valve becuz I bought the Explorer used and dont no if the person who owned it ever changed the oil often...My Father had mentioned something about the idle air control valve. I believe thats on the air cleaner.

ThaNk you for yur help

The PCV is located behind the intake on the passenger side.
