they can be cleaned, if it has been standing a while soak 'em in injector cleaner to start with, it is worth a go, but they will probably need an untra sonic clean and injector cleaner pumping through them. someone around here was making an injector cleaning rig a while ago.

If it is only firing on four then bear in mind the system fires each bank of injectors alternately, so you may not have a sticky injector problem. It could be a fault in wiring, injector resistors or ECU.
Check that all the injectors are receiving their injector pulse befor you assume the injector is faulty.
Removing spark plugs leads one at a time to detect if any changes to engine note occur to determine which cylinders were not firing.
You might also get a similar diagnosis by removing injector plugs one at a time.
