Early Models

NOTE:

^ Early model year vehicles have an oil filled ignition coil, mounted on the fender well.

^ Late model year convertibles have an epoxy ignition coil, mounted on the thermostat housing.




NOTE: Check curb idle speed before proceeding to the following procedures. If the idle speed is not within specifications, see COMPUTERIZED ENGINE CONTROLS for diagnosis.

1. Place transmission in neutral and turn off all lights and accessories.
2. Connect timing light to number 1 cylinder. Refer to timing light manufacturer's instructions for proper connecting procedures.

Coolant Temperature Sensor:

3. Start engine and allow to warm up to normal operating temperature.
4. Disconnect coolant temperature sensor electrical connector on thermostat housing. The CHECK ENGINE lamp on the instrument panel should illuminate once this sensor has been disconnected. Coolant fan will come on and stay on throughout the procedure.

Timing Scale:

Distributor Hold-Down:

5. Check timing through timing window in transaxle bellhousing. If timing is within 2° of specifications do not adjust. If timing is incorrect, loosen distributor hold-down bolt and rotate distributor housing until correct timing specification is obtained. Refer to SPECIFICATIONS.
6. Tighten distributor hold-down bolt, and recheck timing. Reconnect coolant temperature sensor electrical connector, and erase any fault codes that may have been set. For clearing fault codes see COMPUTERIZED ENGINE CONTROLS.

NOTE: There is an additional socket in the bellhousing of the transaxle, it is a socket for a magnetic timing probe. Do not set the timing through this socket with a standard timing light. This socket is positioned 10 degrees ATDC and will yield inaccurate timing specifications if used with a standard timing light.
