WARNING: This page is about a different car, the 1997 Infiniti I30. However, it is still accessible from the selected car via links, so may be relevant.
ECM controls ignition timing advance based upon sensor input signals that reflect ignition timing needs. If timing problems are experienced, inspect input signals for proper operation. See TIMING ADVANCE SYSTEM INPUT SIGNALS table. To check input signals, see ENGINE SENSORS & SWITCHES or ECM pin voltage charts in PIN VOLTAGE CHARTS article.
