This has been happening to my car as well. It typically happens when your oxygen sensors start to wear out. Mine does it once in a while and I have the local auto store reset it. Go to your nearest auto store and have them tell you what code it is and ask them to reset the OBD so the light goes out. If the light comes on right away and the code has to do with your oxygen sensors, have them replaced. There are three, two are easy to replace, one takes some effort as it is in a tough to get to spot. The dealer will charge you a fortune to replace them so do it yourself or through a local mechanic. It is a very simple task other then the access.

#4 Miss-fire. All the things you are saying make a lot of sense. When the light is blinking the cylinder is actualy misfiring, & the smell you are smelling is the fuel that is not burning in the engine burning in the exahst. This can cause a lot of damage to the exausht if it is not repaired..
There is still a couple of things that need to be checked, first he needs to check to see if it is possibly a fuel injector that is sticking. He can do this easily by moving the #4 injector to another cylinder & run the car. When it starts missfiring he will need to see if it is still #4 or if it is the cylinder that he moved the injector to. if it is the new cylinder it is obviously the injector, if it is still #4 he will need to look into the possibility of the EGR valve sticking open or some other issue to do with valve timing or low compression.
I hope this helps
