Engine flooding
 

hello,
i'm having engine flooding trouble, it seems the injectors are slowly leaking fuel when the engine is turned off. it stops when there is no more pressure in the fuel rail. I thought it could be a dirty injector that could be leaking but all 4 are doing it. Has anyone had this problem?
i'm using 450cc low impedence injectors from a 94 talon tsi (BL450) with a honda resistor box http://www.hondatuningmagazine.com/t.../photo_04.html

i tried putting back in the stock injectors with the stock wiring harness and the problem stopped...
could it be because of the resistor box or is this normal for this model of injector?
