Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.
Allow the engine to cool if it has been running.

2. Inspect Engine Mounts

Use a socket set to remove any covers obstructing access to the engine mounts.
Visually inspect each engine mount for cracks, tears, or excessive wear.
Use a pry bar to gently move the engine and assess mount flexibility.
Replace any damaged mounts with OEM or equivalent parts, ensuring they are torqued to manufacturer specifications.

3. Replace Spark Plugs and Ignition Coils

Remove the ignition coil covers using a socket set.
Disconnect the electrical connectors from each ignition coil and remove them.
Remove the old spark plugs using a spark plug socket.
Install new spark plugs, ensuring they are gapped correctly according to manufacturer specifications.
Reinstall ignition coils, making sure connectors are secure.

4. Clean Fuel Injectors

Use a fuel injector cleaning kit or replace injectors if clogged.
Follow the kit's instructions to ensure proper cleaning.
If replacing, disconnect fuel lines and electrical connectors before removing old injectors.

5. Check and Replace Air Filter

Locate the air filter housing and remove the cover using a screwdriver or socket.
Inspect the air filter; replace if dirty or clogged.
Reassemble the air filter housing securely.
