Isn't this what happened on the ecoboost trucks? Water in the cooler, old people driving the trucks around trying to get 45mpg, and then when they NEED the power to get out of the way or something the truck would shutter before actually taking off. Condensation would puddle up inside the cooler.
They fixed it by blocking part of the intercooler, which sounds like the worst thing ever, but... It fixed the issue, lol
