let it cool down a bit before shutting it down,and or tune up. check timing
Your engine may be running too rich. Has your gas mileage gone down?
try using higher octane fuel
There is now straight forward answer for this question, ignition timing,fuel mixture,valve timing,computer prom,and many other factores can contribute to dieseling. A Tech would need more info. to properly diagnose the problem. For example, mileage,type of fuel & ignition system,. I will say that most dieseling can be contributed to poor octane of fuel or timing.
I had the same problem on my old truck. When you shut the engine off it starts dieseling.Check the carburetor and see if the bottom butterflies are shutting all the way, if not try adjusting it or find out why they are not shutting . This is the most common cause of your problem.

How to stop corvette engine dieseling problem?
the solution can depend on the year and induction type. usually too high an idle speed and rich idle mixture combine to allow a hot carbon chunk in the cylinder to ignite the mix and cause the dieseling. on injected engine its far less common but leaky injectors have been known to cause the condition also
Why won't my 1995 F-150 stop running?
This condition is called "dieseling" where the engine continues to run on after the ignition key has been turned off. It means that your engine timing is way off ... a complete tune-up of this engine should end this situation.
1967 Cadillac engine wont turn off?
If the engine continues to run after you have turned the key off you have what was called "Dieseling". Checking the timing and set the idle to factory specs should cure it. Shutting the engine off while stopped in drive will stop the engine for now until you get it looked at.

Several things can cause this phenomenon, called dieseling. Built up carbon in the cylinders, incorrect timing, an overheated engine, a lean carburetor setting, or a fast idle can all be contributors to dieseling.?æ

The term for this is called "dieseling" ... nothing to do with a diesel engine, rather it's a timing issue with your cars engine.
Why is it that when you turn the car off its still running in a1992 Honda Accord?
Dieseling or "Run-on" occurs when the engine is so hot that the fuel in the engine ignites without the spark plugs firing. On newer cars, like this '92 Honda, there should be an anti-dieseling valve that will turn off the fuel. That might have failed and will need to be replaced. After your engine has cooled, check the coolant level. If the coolant is too low, it can contribute to the engine overheating. If the radiator fan is not running while your car is dieseling you can bank on problems with the cooling system. The '92 accord, I believe, still has a thermostat switch that turns the electric radiator fan on. That could be bad or the fan could be burned out.
What makes an older Johnson 60HP motor keep on running after the ignition is off and the spark plug wires disconnecte It also revs up to more than normal RPM's?
It sounds like your engine is "dieseling". It's where a gasoline engine runs after any normal source of ignition is removed. Dieseling is often caused by carbon build up in the cylinder (on the head). After the engine has been run, the carbon stays red hot and continues to ignite the fuel.
Why does your car want to start when you turn it off?
The problem is called "dieseling" or "engine run-on" and happens primarily in cars with carburetor engines. It occurs when the engine is shut down because fuel in the cylinders is being ignited without a spark, but by a hot spot in the cylinder. The problem isn't as prevalent in cars after 1990, since most are now fuel-injected.There are several things that can cause dieseling - refer to the link below to view them.
Why does 1995 Lincoln not shut off when key removed?
When the key is turned off and the engine continues to run normally it is probably an electrical problem like a bad ignition switch. However, if the engine is "dieseling" and the ignition is really off, then the problem may be a buildup of carbon deposits on the tops of the pistons and the head and spark plugs. You might try cleaning or replacing the spark plugs, then use a higher octane gasoline. But to simply stop the dieseling just turn off the ignition with the transmission in 'drive', then shift to 'park' after the engine has stopped turning over. The timing is too far advanced. Take it to a shop and find out why the timing is so far above top dead center.
