actually, the DP will not fix injector problems that require cleaning, but it will help some with injector problems, but what it does that BRAND NEW injectors will not fix is it cleans out the prechambers, and the combustion chambers. if you want to just rebuild the injectors, put some marvel mystery oil in the pc's and let it settle for a day or so, then flush some pb blaster or WD-40 through with the injectors out, crank over the motor and this will make a really poor running car run really well.
or just dump in the DP and let it do it's magic for less work.
