The seven bottles of injector cleaner on an empty tank is part of your problem, it won't burn that concentrated.

Put a bottle of Techron or RedLine (these are the only two with the proper detergent) in and fill the tank with nice, high grade premium. Drive it out, then repeat, then run a full tank of clean permium, THEN check the plugs (unless you have black smoke rolling out the back). This will give you a better idea of how things are working after running a bit.

Heavier oil and a nice hour long freeway run (at speed, not stop and go) will probably clear the plugs up some, too.
