2003 Ford Windstar Engine light

Ok here is the story. Engine light was blinking today after I went thru a few puddles. Car's acceleration was sluggish and the car felt like it wanted to stall out, was bucking a little whenever I stopped. When I stopped at a light I would put the car in neutral and give it a little gas, sometimes the engine light stopped blinking. Car is has enough oil, is not overheating. I am wondering if this is just a case of the engine getting wet, or if it could be symptomatic of some other problem. Than you very much for any help you can provide.
