Tune-Up Notes
NOTE:
When performing tune-up procedures described in this article, the following notes and precautions must be followed:
Due to late changes, always refer to Engine Tune-Up Decal in engine compartment before performing tune-up. If manual and decal differ, use decal specifications.
With the exception of initial ignition timing, normal tune-up procedures are not required. Adjust fuel system only when indicated by the computer Command Control (CCC) System Performance Check or poor engine performance.
Damage to the HEI electronic module and/or coil may result if "TACH" terminal is grounded. Do not remove spark plug wires with engine running. This would cause an overly rich mixture which may damage catalytic converter.
Before making compression test, or cranking engine with a remote starter switch, disconnect the "BATT" terminal connector from distributor.
