Sounds like it's POSESSED! Or maybe it's what they call deiseling. Does it do it right after you shut it off?
Here's website definition of causes.
DIESELING, also called after-running or run-on, is a problem when the engine keeps running after the key is turned off. A knocking, coughing, or fluttering noise may be heard, as the fuel ignites and the crankshaft spins. When dieseling, the engine ignites the fuel from heat and pressure, somewhat like a diesel engine. With the key off, the engine runs without voltage to the spark plugs. The most common causes of dieseling are high idle speed, carbon deposits in the combustion chambers, low octane fuel, overheated engine, or spark plugs with too high of a heat range.
You might try shutting it off while still in drive just before you put it in park. As a temporary solution.
