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.

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.

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.
