What should the Ignition Advance or Cam Retard Offset be on a 1996 Chev Tahoe 5.7L at idle speed?
This truck has a computer controlled timing system. The timing
is set at a base 0-2 degrees with the timing connector unplugged
(single brown wire with a disconnect - usually under the passneger
dash) Once you manually set & tighten the distributor at 0-2
degrees.... plug the timing connector back together. The timing at
idle should now move to 10 degrees - give or take a degree.
