So I realized in my stupor that while trying to flush the coolant system in a 93 5.0 I put the flush kit on what I think is the egr valve and ran water through it and water started coming out of the exhaust. I haven't tried to start the car but I realize I did this wrong and I feel like the biggest idiot ever. Did I just screw everything up?? I attached it to this hose by mistake thinking it was the heater hose.
