4.0 in BII idles funny for first 2 minutes

[Mr.Steven]

So I took my bronco through about a foot and a half + deep mu hole yesterday. It got a little hot and the mud is now everywhere in the engine compartment even after spraying it off. When it starts up it has a low choppy idle as opposed to the high idle that helps it warm up faster. I did go through the hole backwards too. The wierd idle goes away after about two minutes and it runs perfect.
