4. Align the timing marks on the timing belt cover and the crankshaft pulley.
5. Start the engine, warm it up to normal operating temperature and measure the idle speed. Point the stroboscope light at the pointer with the ignition advance scale and the crankshaft pulley. The mark on the pulley should align with the S mark on the pointer scale. If necessary, loosen the distributor mounting bolt and slowly turn the distributor until the mark on the crankshaft pulley aligns with the S mark on the pointer.
6. Remove the additional shorting wire from the diagnostic connector and check that the ignition timing has moved forward by 12 to 22 degrees.
7. Turn off the engine and remove the tachometer and strobe light.
