I have a 1997 Camaro z28, A4. Last night as I was coming home and the engine started knocking severely. I then saw white smoke coming out of my engine bay so I shut it off right away. My temperature gauge was in the red as well. The next morning i noticed that as the car was on, whenever I gave it a little gass it would bog and die. Now it runs smoothly but im afraid to drive it, please help :/. I checked my oil and coolant, both seem normal. Im stumped.
