Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal.

2. Inspect and Replace Spark Plugs

Remove the ignition coil covers (if applicable) using a socket set.
Disconnect the ignition coils and remove them from the spark plugs.
Use a spark plug socket to remove the spark plugs.
Inspect the spark plugs for wear and replace them if necessary with OEM parts.
Reinstall the spark plugs and ignition coils, ensuring they are properly torqued (typically 12-15 lb-ft).

3. Check Engine Mounts

Visually inspect the engine mounts for cracks or separation.
If damaged, remove the bolts securing the engine mounts using a socket set.
Replace with new mounts and torque to manufacturer specifications.

4. Vacuum Leak Inspection

Start the engine and visually inspect vacuum hoses for cracks or disconnections.
If any leaks are found, replace the affected hoses.
Use a smoke machine for more difficult-to-detect leaks, sealing any identified issues.

5. Clean Throttle Body

Remove the air intake duct connected to the throttle body using a screwdriver.
Spray throttle body cleaner onto a clean cloth and wipe the inside of the throttle body to remove carbon buildup.
Reattach the air intake duct and re-connect any sensors.
