I own a 2005 322 Cruiser. Recently several of my gauges have started to act erratic. When the throttle is advanced one of the engines will show about a 1000 RMPs less and fluctuate. however it is clear that the engines are running even. If you tap the dashboard they will sync. Similarity fuel gauges indicate intermittently, the trim tab indicators only work intermittently also. Has anyone else seen a similar issue. I am wondering if there is a common ground for these indicators that may be loose under the panel. Any ideas? Thanks.
