98 EXPLORER ROUGH IDLE WHEN COLD

I HAVE A 98 EXPLORER THAT WON'T IDLE WORTH A DAMN WHEN IT IS COLD (BELOW 60 DEGREES). THIS ONLY HAPPENS THE FIRST TIME IT IS STARTED OR WHEN IT HAS SAT FOR SEVERAL HOURS (4 OR MORE). THE FUNNY THING IS THAT IT SMOOTHS OUT WHEN IT IS PUT IN GEAR. IT IS A 98 4.0 WITH OVERHEAD VALVE AND 50,000 MILES ON IT. ANYONE HAVE ANY SUGGESTIONS?

Clean your MAF and IAC. While you are cleaning them, disconnect your battery to have the ECU reset itself after you re install the MAF and IAC.
