Simple engine tune up
- Air Filter
- Distributor Cap
- Distributor Rotor
- Spark Plug
- Spark Plug Gapper
- Spark Plug Wire Puller
With the engine off and cold, open the hood & locate the air filter, the spark plugs, ignition coil (or coil pack) and the distributor cap and rotor (if applicable). These are the parts most commonly replaced when performing a basic engine tune-up.
Locate the airbox and release the airbox clips or remove screws and remove the air filter box cover. Remove the air filter.
Vacuum first, then wipe out the air filter box to remove all debris. Install the new air filter and re-install the filter box cover.
Grab the spark plug wire boot and remove the wire from the plug. Remove the spark plug from the cylinder head using a ratchet, spark plug socket, and socket extension.
Check the gap on the new spark plug and adjust as necessary to specification.

Apply a small amount of anti-seize compound to the plug threads. Thread the new spark plug in by hand and then tighten it to the recommended torque with a socket and ratchet / torque wrench. If necessary, you may use a length of vacuum hose to help the spark plug installation into the threads. Reconnect the spark plug wire. Repeat for the rest of the spark plugs.
If applicable, remove the distributor cap with the wires attached. Replace the rotor and install the new cap. Transfer the wires from the old cap to the new cap one at a time. Do not mix up the wires.
Hopefully now you have a good understanding of performing a basic engine tune.
