When I am at idle and blip the throttle, there is a hesitation in which it seems like my engine is dumping a lot of fuel or being starved from fuel. Also when I am crusing and suddenly mash the gas pedal, my car would bog and then start picking up. I am running 450cc injectors, inline and intank pump, vafc, and 4:1 fmu. I am thinking maybe one of my injectors are leaking or stuck open. I also hear a distinct ticking from the injector area. Anyone care to diagnose?

 

way to rich . . . . ditch the FMU since you have a VAFC . . . no need for both, but if you feel you need both then take some fuel away on the VAFC so you arn't running so rich

Pull your plugs guarantee they are black
