I did a tune u on the car and when I did the cap and rotor when I tightened the rotor it turned and put the car out of timing. How can I put it back on timing myself?
Do you

LS400 & SC400 1. Connect timing light to No. 6 spark plug wire. Connect tachometer to IG- terminal of engine check connector. Bring engine to normal operating temperature. See Fig. 13 or Fig. 15 . 2. Install jumper wire between terminals TE1 and E1 of engine check connector. See Fig. 14 or Fig. 16 . Ensure idle speed is within specification. See IDLE SPEED SPECIFICATIONS table under IDLE SPEED & MIXTURE. Ensure base timing is within specification. See IGNITION TIMING table under ES300. Remove jumper wire from engine check connector. 3. If ignition timing is not within specifications, check the following: Ensure throttle valve is fully closed. Ensure there is continuity between terminals IDL and E2 of throttle position sensor. Check valve timing. CAUTION: Some tachometers may not be compatible with ignition system. Consult tachometer manufacturer before connecting tachometer to system. DO NOT allow tachometer terminal to become grounded, or damage to ignitor and/or coil may occur. Base timing is 8-12 degrees BTDC at 600-700rpm.
