So i added about a 3rd of seafoam into the break booster vaccum with the car running and shut it off and left it in for about 20 minutes and my car started right away and only a little bit of smoke came out but it stopped quick and then it was spitting liquid out of the exhaust not much but some was coming out.. anyone know whats up? is my car really that clean? lol let me know what you think thanks..
