Ignition Timing

ADJUSTMENT

NOTE: If the information given in the following procedures differs from that on the emission information label located in the engine compartment, follow the directions given on the label. The label often reflects production changes made during the model year.

Except 2.3L Engines

1. Apply the parking brake. If equipped with a manual transaxle, place the shifter in the neutral position. If equipped with an automatic transaxle, place the shift lever in P.
2. Locate the timing marks on the crankshaft pulley and timing belt lower cover. The engine may have to be cranked slightly to see the mark on the crankshaft pulley.
3. Start the engine and allow it to come to normal operating temperature. Be sure all accessories are OFF.

4. Check the idle speed and adjust, if necessary.
5. Turn the engine OFF.
6. On all engines except 2.0L engine with an automatic transaxle, connect a jumper wire between the TEN terminal and the GND terminal at the underhood diagnosis connector.
7. On the 2.0L engine with an automatic transaxle, remove the shorting bar from the double wire SPOUT connector.
8. Connect an inductive timing light according to the manufacturer's instructions.

9. Start the engine and allow the idle to stabilize. Aim the timing light at the timing marks.
10. The mark on the crankshaft pulley should align with the specified Before Top Dead Center (BTDC) degree mark on the timing cover scale, plus or minus 1 degree. If the marks are within alignment proceed with step 13. If the marks are not aligned, proceed to Step 12.

11. Loosen the distributor lockbolts just enough to turn the distributor. While aiming the timing light at the timing marks, turn the distributor until the marks are aligned. Tighten the distributor lockbolts to 14–19 ft. lbs. (19–25 Nm) and recheck the timing.
12. The ignition timing is now set. Disconnect the jumper wire from the underhood diagnosis connector or install the shorting bar from the double wire SPOUT connector.
13. Remove all test equipment.

2.3L Engines

The 2.3L engine utilizes individual ignition coils for each cylinder. The timing is controlled by the computer. Ignition timing adjustment is not possible or necessary.
