Rough Idle? Washing?

I was washing my JK Rubi 4dr this weekend (I know, I is a Jeep) ---
Anyhow about an hour later, I moved in into the garage after I got done fooling around with the hardtop and Raingler nets......

It started running rough on the idle, like it wanted to die......I stepped in and applied some throttle to try to clear it, and it seemed OK. Driven it since and don't notice any issues......Mileage was about 800 on the engine at the time of the high pressure washing or engine cleaning, just exterior with good handwash.

Probably a fluke, but wanted to see if idling issues were common or cause for concerns on the 3.8Ls.....

Isolated case, maybe a loose plug wire, etc on yours, check everything real good. Washed my Rubi engine bay several times when it's cooled down, never had any issues.

Didn't seem like bad gas.....sounded like a vacuum/loose line issue to be honest.
It cleared up OK ---- haven't noticed it since.
