Strange Idleing problem

05 F250 v10 auto.

Started the truck today and put it right into reverse to back out and it felt like it was missing. So I put it back into park and the mis went away. So back into reverse and the mis came back. I gave it a little gas and it cleared up.

This is the second time that this has happened the last being 6 weeks ago. Any thoughts?

Sticky IAC is my first thought. The gunk hasn't warmed up enough for the valve to move and you're putting a slight load on it causing the idle to drop.

Call your dealer.... Ask them how much it would cost to fix your Weeble Shaft and Muffle Bearings... Shoot, i'd even ask them how to change your Kunueter Oil to be on the safe side.... ...... Ask for the New KoJo Intake too... it is supposed to help stuff similar to your problem. One more thing... Go buy Kojo Bearings, sounds like they are all outta wack!
