Without a fuel injector tester the only thing you can do is remove all of the injectors, leave them connected to the fuel distributer, put each in a container to catch the fuel, disconnect the ignition coil, and try to start the motor. Observe each for a cone-shaped pattern and compare the amount of fuel each injector puts out. This is a more dangerous and less precise way of checking the injectors. If the engine is not idling smoothly, ie: it seems to have a "bump" or dead spot then you may have a bad or dirty injector. It would be best to send out to a vendor so they can test and clean the injectors. The injector tester can give you the precise operating pressures which also affect idle quality, if they are not all close to each other you can't tell that directly any other way.
