Some weirdies do happen on mine, but only slight. I must be cautious with fuel because it starts pumping air now when needle enters the orange section..and a full fillup bumps the needle way past the top. And the oil pressure needle hesitates to low levels at times....no other problems though, and I was thinking the sensors were going haywire....I might reconsider.
