Hard to say. If you mean it keeps running after you turn the key off it sounds like it's all carboned up. The carbon (inside the cylinders) gets hot and acts like little spark plugs and keeps the engine running and knocking a while. If it does this all the time I suggest you do a compression check to see if it has a bad timing chain.
