02 Wrx Rough Idle/ Stalling after fmic install
I own a 2002 Subaru Wrx. Recently I installed a Turbo XS Fmic, and now I have a rough idle and when the idle does level out it runs smoothly for 1-4 mins before stalling out. I have hooked up to a scan tool to the car, and it shows a code that the vechile is running lean. I have a Walbro 255 fuel pump on the way. My question is, will the fuel pump be enough to resolve the issue, or will Sti pink injectors and a tune be needed to correct this problem. Other mods on the car are a apexi cat back exhaust system, Blitz turbo timer, Turbo XS boost controller, and AEM intake.
