Ignition Timing: Testing and Inspection

2. Pull out the service check connector located under the dash on the right side. Connect the WHT and BLK terminals with a jumper wire.




3. Connect a timing light to the service loop; while the engine idles, point the light toward the pointer on the timing belt cover.
4. Check the idle speed.

NOTE: Adjust the idle speed, if necessary, by turning the idle adjusting screw.




5. Inspect ignition timing at idle speed.
