REMOVAL
CAUTION: Base ignition timing is not adjustable on
any engine. Distributors do not have built in centrif­
ugal or vacuum assisted advance. Base ignition
timing and timing advance are controlled by the
powertrain control module (PCM). Because a con­
ventional timing light can not be used to adjust dis­
tributor position after installation, note position of
distributor before removal.
(1) Disconnect negative battery cable at battery.
(2) Remove air cleaner assembly and connecting
tubes.
(3) Remove the spark plug cables and secondary
ignition coil cable at distributor cap. Mark position of
cables before removal. Position spark plug cables to
the side of engine.
(4) Remove distributor cap from distributor (two
screws).
(5) Mark the position of distributor housing in
relationship to engine or dash panel. This is done
to aid in installation.
Before distributor is removed, the number one cyl­
inder must be brought to the top dead center (TDC)
firing position.
(6) Attach a socket to the Crankshaft Vibration
Damper mounting bolt.
(7) Slowly rotate engine clockwise, as viewed from
front, until indicating mark on crankshaft vibration
damper is aligned to 0 degree (TDC) mark on timing
chain cover (Fig. 11).

(8) The distributor rotor should now be aligned to
the CYL. NO. 1 alignment mark (stamped) into the
camshaft position sensor (Fig. 12). If not, rotate the
crankshaft through another complete 360 degree
