1992 Chevy Truck S10/T10 P/U 2WD V6-262 4.3L VIN Z
Ignition Timing Specifications, Electrical: Timing Specifications
Base Timing ........................................................... 0° TDC


Set timing under the following conditions:

^ Normal operating temperature.
^ Air cleaner installed.
^ A/C "OFF".
^ Transmission in neutral.
^ Disconnect the SET TIMING connector (tan/black wire), taped to the harness below the heater case in the passenger compartment. DO NOT disconnect 4 wire connector at distributor.

Connect timing light and adjust to specification by loosening hold down bolt and rotating distributor.

Tighten hold down and recheck the timing. Stop the engine and connect SET TIMING connector. Clear ECM trouble code by disconnecting ECM power source. With engine at operating temperature, drive vehicle at part throttle with moderate acceleration and decelerate to idle condition. This will "teach" the ECM/VCM and return the engine to normal performance.
