I have a 01 F4i ( fuel injected not carbed ), and im stuck on this fueling issue.
Its very boggy with low RPM, sounds like a damn subaru, i dont have modified exhaust just a SBK slip on. Im getting frustrated,
I've changed the fuel pump, the voltage rectifier, and i just changed the pressure regulator.
I've adjusted the idle screw to about 1500 rpm. I've researched everyone elses problem but im not seeing possible answers. Can anyone please give anymore possible answers? Thank you for your time.
