Fuel Pressure Gauge bouncing 60-100 My FP gauge is bouncing back and forth between 60-100 psi but at wot it drops to about 55psi and now my air-fuel is pegged to rich and never even moves. It was working fine when i put vette 02 sensors in bout a year ago. What would make my gauges do this and where do i start looking to fix? AF gauge is am auto meter and FP gauge is a flebay street glow.
