I had some sticky auto ignition switch issues recently, so I squirted some Fluid Film into the key slot, and worked it a bunch. Didn't fix it. At the same time, I needed to get a second key cut, and when the locksmith guy (it was a trick auto key, so I went to a locksmith...) came out to test it, I showed him the key problems with the original key. He came back with some WD 40. I kept my mouth shut. It worked like a charm, and has ever since. Go figure.
But, the ground and FF advice sounds good to me! Iffy vehicle electrics often are traced to poor grounds or corroded power contacts, and not the gauges themselves- especially when they're intermittent or, even better, more than one gauge.
Yes, the more than one gauge is extremely suspicious of either a very flakey key switch not putting full voltage to the gauge, or some corroded ground connection. I say lets fix the key switch one way or another first then start hunting down the gauge problem if it still persists.
