I'm not sure if It's me, but has anyone noticed a change in performance with temperature/humidity levels? I'm sure as with any electronic device that extreme temperatures cause behavior issues, but since the crisp cool days of fall have begun, I seem to be finding more. It would appear that my sovereign has less" erratic behavior" and increased steady target identification. Almost like a four barrel 350 Chevy engine on a cold day! She just wants to run.Also would battery performance be effected as well? Anyone else notice any different behavior with the weather?
