I have a 94 gsr turbo, everything starts normal and idles fine. The car runs good when it's cold but when after it warms up a bit, it starts to hesitate around 3k rpms. I have a wideband , The car runs lean on start up at 12 and its continuous, the car will lean out and my wideband reads 17-18 and will lean out. I'm running a 1200 cc rc injector with resistor box, it's all tuned and I have a gsr fuel pump. I'm wondering if I'm not getting enough fuel from the pump or if the injectors are failing. Which should I do first?
