Reattach the housing cover and tighten the screws.

3. Clean or Replace Fuel Injectors

If cleaning, use a fuel injector cleaning kit; follow the kit instructions.
If replacing, disconnect the fuel lines and electrical connectors from the injectors.
Remove the old injectors using a socket set and install new ones.
Reconnect fuel lines and electrical connectors carefully.

4. Replace Spark Plugs

Remove the ignition coil or spark plug wires carefully.
Use a spark plug socket to remove the old spark plugs.
Check the gap on new spark plugs before installation and adjust if necessary.
