"says here on your chart"
okay so my car overheated today, so i think it is my waterpump or the radiator. the only problem now is that my car makes a knocking sound when i push the gas and black smoke comes out of my tailpipe. now i am not an expert but i am pretty sure i fried something, my only question is what? i know that black smoke means that usually it is running lean but i don't think that is it since i have a knocking noise. so if anybody has any ideas let me know i am screwed here.
