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 the engine is knocking really loud you probably need to overhaul the entire engine or get a new or used engine because loud knocking is not good
if it is making a loud knocking noise it is about to go out If when you put it in to gear, it jumps in to it and the car starts to move instantly then the converter may be shot.
