My autometer gauge acts funny. It fluctuates back and forth. With my blower connected and without it. It is connected directly to the 02 sensor wire. I think that is fine, because the Edelbrock and K&N air fuel ratio gauges are connected directly to an 02 also. Am I correct?

In closed loop mode, the O2 gauge fluctuates between approx 0 & 1 volt, as the computer changes the mixture ratio. @ WOT, the voltage should be somewhat constant @ near 0.9 volts.
