[s-cars] wonky temp guage

[theringmeister at triad.rr.com]

when this happened on my cq it was the MFTS.  Not sure if that applies to the AAN, but it was the exact same behavior.  Whatever is driving your gauge is bad, or the connections are loose at the very least.  I'd try cleaning them once you find out what sender is responsible for signaling that gauge.
