Why is my 1992 BMW 325i burning fuel excessively?

This isn't a major problem but this car will sometimes get horrible gas mileage during "city"-like stop and go driving. It averages 20mpg city but sometimes it will only get like 10mpg and I'm feathering the gas pedal but the things burning unessesarily rich or something and it pisses me off a little. There's quite a few miles on the engine but it was recently rebuilt, save for the intake manifold, and the fuel injectors are stock I believe so I'm thinking maybe clogged/bad injectors? or fuel filter? Should I try injector cleaners first before getting a set of injectors? What is the best and most worthwhile fuel system/injector cleaner I could purchase from autozone? Thanks a heap!!
