My car will stall and then accelerate very quickly. If I am driving and trying to accelerate my car will stall almost cutting off. This usually happens around a speed of 25/30 mile per hour. I also experienced deceleration while driving on the highway at 60/65 mph. This is very scary. Also when I am in reverse my transmission makes a knocking sound. My engine light constantly comes on. Heat vapors comes from the hood of the car.
