sounds like you have a vacuum leak.

 

a vaccum leak would cause the car to dam near drive it self like taht ... how so plase explain

 

well if it is indeed a vacume leak it will cause the engine to surge by introducing more air with the gas mixture. to find out where it is you could buy some carb and choke cleaner and spray around vacuume lines and the engine will surge when you spray around the leak.
