What is the solution for a knocking noise in the engine?
Usually, a knocking engine is very bad, and requires replacement or rebuild of the engine. If the engine is going "clank-clank-clank" at idle, and the sound gets louder when you get on the gas and disappears for a sec or two when you let off, that means you gotta replace the engine. You ain't gonna go for but a couple more miles before you throw a rod....

What could cause a knocking noise in the engine?
Knocking is caused by preignition, where the heat in the cylinder causes the gas to ignite before the spark plug does. The noise could also be piston slap, which is caused by a worn cylinder wall. Try using a higher octane/grade gas and see if the noise goes away. In certain engines like the Malibu 3.1 liter and others, the knocking is caused by a piston rocking in the cylinder. This is called piston slap. It is a damaging condition, but seems to be considered "normal" by GM.
