Gauges erratic

Hi All,

I have a set of AEM gauges installed in my 85 Alfa Spider. About 1500 miles on a fresh engine.

I am getting erratic readings pretty consitantly. Oil pressure will fluctuate 10 psi or so at constant rpm. Coolant temp can jump around by 20 degrees. And the AFR is just crazy most of the time. Oil and temp just happen periodically, while the AFR is always jumping around.

I checked voltage, the AQ1 wiring, etc. 

Any ideas?

Thanks, KJM
