Air Intake Sucked in Water

I was washing out under my hood with a hose because it was muddy. After I was done my "check engine" light was on and my exhaust pipe was dripping/spraying out water. What do I do?

If the engine runs ok, not enough water made it into the engine to worry about. The exhaust will often drip out accumulated moisture until it burns off when the engine gets fully warmed up.

So far as the Check Engine light goes, it's likely just from moisture in a connector somewhere in the engine compartment from hosing the engine off. It can sometimes take several hours or even several days for moisture to work its way out of electrical connectors under the hood which can even cause misfires in addition to a Check Engine light.

When you have a choice, buy American.

did you start it? you'd have to try pretty hard to fill the air intake box with water, and even then, it would have to travel up another few inches. i'd start by removing your air filter and see if there is water in your air box

If your TJ has a distributor, I would pull the cap off and see if you got water in there. I always cover my distributor cap with a plastic bag before I wash the engine as I have had problems in the past with other vehicles getting water in there, especially if using a pressure washer.
