I recently had a similar problem on my Syncro.  The temp gauge would
hover 1-2 needle-widths above the LED.  Replacing the Temp2 sensor had
little effect.  To make a long story short, I solved it by replacing the
two large ground points behind the fuse box under the dash.  I also
ended up replacing several of the corroded spade connectors, which were
so brittle from corrosion that they broke apart.  It's a PITA to do, but
I will never overlook this on another van.  My Syncro temp gauge now
sits right on the LED in the 115F desert heat.
