spuggy,
yes I did do a back flush fro the technique I got from a great fellow and porsche enthusiast of which his name escapes me know, and basically what you do is get a pc of (1 strand) 18 awg wire, use a tweezer tip or such to lift the pintel top up off the injector seat and la-sew the pintel tip, pull the wire strands down the side of the injector, push a 12" long pc of 5/8" id rubber hose down over the pintel end and the wire so as to keep the pintel tip up, fill the hose with berrymans or any other cars cleaner~solvent, put a compressed air hose fitting on the end snuggly and blow 100psi thru the hose, put a rag over the normal fuel input end of the injector and see all of the sh^t that comes out... usually. After this, put the hose on the other end and check the spray pattern out pintel end and check for drips out pintel end when filled cleaner and no air applied.
That is the compressed version. Read it slowly as these are all of the steps and have at it.
This being said, I still bought new injectors for piece of mind and to ensure as evenly as possible the same amount of fuel going into each cylinder as I don't want to burn out a valve or leave any power on the table. These injectors WILL, not maybe, rust, especially with the ethanol in gas now the these injectors are made out of stamped steel. The internal spring on the pintal is steel. Their is a rubber seal on the base where the pintel seats against and these dry out - become hard - basically impede a good seal with the pintel allowing lower pressure to trigger them releasing fuel sooner and longer than spec - hurting performance & wasting gas.
Good luck!
Bob
