So my car has been idleing rough lately and juss not pulling hard like it did. So I checked the timing and it was dead on. I pulled the plugs and noticed that they were pretty white. So I check the fuel pressure and it was at 23psi...really low. I pinched the return line and it jumped up to 33psi. This is a totally stock fuel system, shouldn't it be at 36psi at idle? I think its my fuel pump...any other ideas? Thanks for any help guys.
