Injectors become clogged with fuel residues (something similar to varnish) due to the evaporation of fuel in the injector nozzle when the engine has been stopped. Every time you stop a hot engine a small amount of residue adds to the already present build up. The more frequent the stops, the more rapidly the buildup accumulates. This accumulation eventually reduces the flow of fuel through the injector and disrupts its spray pattern, causing the engine to run lean. This can manifest itself in a number of ways, although the most common is drive-ability problems such as flat spots and hesitations.
