well i linked my hard starting to a leaking injector and i want to know if i should upgrade the injectors rather than replace the oem ones, i alreday have a 255lph fuel pump but wanted to know if the injectors will benefit me in any way other than lowering my gas milage and destroying my cat. and one more thing i wanted to also find out if i only need to modify the primary or do i have to mod them both.

Get them cleaned!

if it an NA then you dont need bigger injectors



if its a turbo you might want slightly bigger secondaries, but you cant really change the primaries without something like an rtek ecu

well whats the easiest way to clean them, i ran an injector cleaner but it didnt do anything, the injectors are still leaking. i was actually looking into a bad fuel pressure regulator and maybe its letting the pressure get to high making the injectors leak.

Pull the injectors and send them to a shop that does injector service, either locally or by mail to a place like RC Engineering. The ones I sent to RC came back looking and working like new.
