02 LTZ tach needle jumpingcableguy4k 09-10-2009, 12:10 PM The needle on my tach has started jumping around. It happens at varying RPM's, even at idle. It does not happen consistantly. Any thoughts? maxwedge 09-10-2009, 12:38 PM Usually caused by the stepper motor in the tach, but check the common ground on the l/s of the block first. vBulletin®, Copyright ©2009, Jelsoft Enterprises Ltd.
