rough idle, need help

[Schobanger]

so, after going mudding with some friends last night, my explorer died a few times due to excess water (we think) in the engine area (and possibly mud). we got it started all the time, and i idled it out at 2500rpms for about 2 mins each time to try and get all the **** out. now, i have a very rough idle, and this morning and on my way home from mudding i had to start off very very slow, and could not take my truck above 2500 rpms without sputtering. now my truck has a rough idle, but is getting better, can now take it up to about 5k rpms which is good. any ideas what could be happening to cause this rough idle?? Thanks in advance boys.

Have you checked if the air filter got wet? I just had my 02 get wet from power washing distort in the housing and screw up the idle and kill about half the horsepower. Check that 1st.
