Tip:Always replace the cap and rotor together — a dirty or pitted rotor causes erratic spark and hesitation regardless of cap condition. These are inexpensive parts and there is no reason to replace only one.
Replacement Procedure
- Before removing the old cap, mark the position of the rotor relative to the distributor body with a paint marker or chalk. This lets you reinstall the cap in the same orientation without disturbing ignition timing.
- Remove the two screws holding the cap to the distributor body. Lift the cap off — the spark plug wires can remain attached to the cap if you move it aside carefully.
- Pull the rotor straight off the distributor shaft. It is held only by friction.
- Push the new rotor firmly onto the shaft. It can only fit in one orientation — do not force it.
- Install the new cap, aligning it to your reference mark. Secure the two screws.
- Start the engine and verify normal idle. If timing feels off, confirm the cap is oriented correctly to your mark.
Note:If you also plan to check base ignition timing, do so after the new cap and rotor are installed. The EF-NS base timing is 7° BTDC at 950 RPM. See the Engine Specifications page for full timing data.
