Good day,
I was wondering if anyone could confirm or deny this for me... Regarding GM¹s poppet injection ?spider¹ system on the 4.3L vortecs, etc., do any of you know if all cylinders receive fuel at the same time? In other words, is it possible to mix up the poppets or if they¹re all working properly, will it make no difference? I didn¹t know if there was actually individual pulsing control from the central injector or if they simply ?fired¹ when they exceed the pressure of the poppet spring itself.
Thanks! Andrew.
