The injectors basically squirt a quantity of fuel based on the pressure given to them an how long the injectors are opened for by the ECU. The chances of them delivering more and then less fuel and back to more fuel independently is going to be slim. Have you put a fuel pressure gauge on the system? Perhaps your fuel pressure reg is going? Have you removed the injectors and test fired them to see if they make a nice 'perfume bottle' spray as opposed to just a jet of fuel? Perhaps is it a faulty engine temp sensor making the ECU feel the engine is in warm up mode, then run mode, then warm up mode...
