A problem arose this past weekend with my water temp and fuel gauges. Upon startup and idle, the water temp and fuel gauges register fine. However, under acceleration and on the freeway, the water temp gauge will start rapidly jumping back and forth (about 25% deflection either side of ambient op temp). The fuel gauge did the same thing on a couple occasions on the freeway WEIRD! Could it be the sending units going bad?
Thanks for any insight.
