A guy showed up at my home , mid December , below freezing temps outside ,driving an older Ford Ranger pickup , tells me his truck is acting up . This is a weekend as well , he then says he installed a water injection kit in his Ranger " it's going to increase my gas mileage ", can't figure out why his check engine light comes on . I tried to explain to him about water ,condensation , freezing temperatures , and catalytic converters .He had the attitude , no matter what you say , you're wrong and I'm right .Told him to unhook the water injector , take it for a highway run , let me know how it turns out . Never got a call back or another visit .
