my setup is a 95 gsr with an 18g greddy turbo kit rc440's walbro255, aem furl rail and fpr, chipped ecu, vafc2 and maybe other little odds and ends. i was running fine yesterday and when i shut my car off everything was fine, but when i started it back up it was idling really liw like between 400 and 500. i tried revving the motor and it takes really long to rev like it has no power. does anyone have any suggestions.
