Don't worry about it...The injectors that are in vehicles are nothing like what is going on in the turbines we use. They really are not injectors at all, but small injection tubes. When the fuel rail becomes clogged really the only way to correct this is for it to be replaced. I f your engine is running fine then just fly. The popping at idle is pretty normal on the RAM engines and some others. Try looking up this topic in the Turbine Clinic forum.

I definitely would not run any form of injection cleaner through the turbine.
