1979 930 Fuel Injector Opening Pressure
So I've taken it upon myself to test pop test all my injectors. I noticed that 4 of my injectors opened up at 40 psi, but 2 injectors opened at 38 psi and 39 psi. Is this bad? Shouldn't they all open up at the same psi or is it that the spray pattern really matters more? I'm just curious. These injectors come from a CIS system on a 79 930.
