TFI IV System

INITIAL TIMING
- Place transmission in NEUTRAL or PARK with Air Conditioner/Heater in OFF position.

Cylinder Numbering And Distributor Location:

Location On Distributor And Firing Order:

- Connect an inductive timing light.
- Disconnect the single wire in-line Spark Output (SPOUT) connector near the distributor.
- Start engine and allow to reach operating temperature.



- With engine at timing rpm, check or adjust initial timing to specification. Specifications

NOTE: To set timing correctly, a remote starter should not be used. Use the ignition key only to start the vehicle. Disconnecting the start wire at the starter relay will cause the ignition module to revert to start mode timing after the vehicle is started. Reconnecting the start wire after the vehicle is running will not correct the timing.

- Reconnect single wire in-line spout connector.
- Check timing advance to verify distributor is advancing beyond the initial setting. If does not, perform EEC IV Quick Test.

- Remove test instruments.
