[s-cars] Speedomter and tachometer are having a dance party without me

[Dave Forgie]

Jason: While this problem could occur because of a cracked line on the
printed circuit board, the fact that you have the same result with a
different instrument cluster leads me to suspect the speed sensor or the
connection to the speed sensor.  The sensor is on the transaxle, left
hand (NAmerica drivers side), above the axle flange, if I remember
correctly.  I would start with cleaning the connection.  If that doesn't
work I would clean and/or replace the sender. (No clue on $$ for a new
one).
