Got out of high school coming home there is a big hill on the way I go home so I go over the hill and at the top of the hill I come to a complete stop when suddenly my car starts to shake like crazy and a screaming nose from my engine when My rpms are low :/

When I got home I open the hood (with car off) and I hear a hissing nose like if air is escaping some where from the engine , I check my oil and its ok, Check my cooling/ anti freeze and put more in waited for another 30 mins turn my car on and it does the same thing again :/ (About to cry cry) But I turn the car off and now I hear no more hissing .. Im so lost and confuse help a kid out guys lol this is my only car I got :/
