Question about my fuel pressure?
With key turned to the on postion, my fuel pressure is 47psi. At idle my pressure climbs to about 52psi. I thought at idle my pressure should drop. When I give some gas the psi ranges from about 56psi to 42psi when I let off the throttle. Bad regulator or have no vaccum in the intake manifold?
