Thanks guys, for your quick response. I'm going to buy that fuel damper. Started to fail after changing injectors and fuel rail. We tuned my car again and keep doing the same. Wideband shows AR sooo lean. VID_20221130_120217.mp4

Hi guys, hope I wish you could help me. Change fuel regulator, fuel pump, dynamics injectors 1050cc, fuel rail (radium) on my skyline R33. It keeps staying lean when warms up. Fuel regulator have kind of pulse and it is undriveable. I'm going to clean my fuel tank and lines, but just trying to find out what could be.
