I would also consider other issues than a clogged injector that could be causing this problem. I would clean the major sensor connectors (Throttle position, Mass Air Flow, MAP (manifold absolute pressure), Cam angle sensor, ignitor,etc.) as well as the injector connectors. After sitting 6 yrs, the normal humidity in the air can corrode the connections and you will go nuts trying to find the gremlins this alone can cause.
I would also ohm out the injectors. I am not sure whether your injectors are high or low impedance, but put an ohm meter across the injector terminals (do this while the connector is off for cleaning), and see what it measures. Write down each and notice if one is significantly above/below the others.
