Check Engine Light
 

Ok guys, I have a problem. I sent my car to a mechanincs class to get cleaned, and I think they pressure washed the engine compartment. Now every time is rains or there is humidity, I have a check engine light and my car barely idles. After I get up to speed and keep my foot on the gas everything is fine, but as soon as I let off the light comes on and I get crappy idling. I think it might be my ecu, but any coments would be appreciated. Thanks tons
