I have a 1993 Ford Taurus with V-6. Its been sitting for over a year. After charging it and adding fuel injection cleaner to the gas, it cranked right up. After driving it for about 15 min, it started spark knocking to the point where sounds like a valve and cuts off. once it cools off it runs fine. As it gets hotter, the knocking gets worse until it finally cuts off again. What could cause this?
