High idle problem

[Jackrabbit41]

I jumped into my jeep this morning and started her up. It idles and runs at a very high rpm. It wasn't doing this the day before but I did wash the engine bay but I drove it the rest of that day and didn't have a problem. What's my problem? What do I do? Thanks y'all! The jeeps been so good lately I guess I'm due for a problem

Tps probably got wet,

Sounds like you knocked off a vacuum hose.
