Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical issues.

2. Inspect Engine Mounts

Use a socket set to remove any components obstructing access to the engine mounts.
Visually inspect each engine mount for cracks, separation, or excessive wear.
Replace any damaged mounts with new OEM or high-quality aftermarket parts.

3. Replace Spark Plugs

Remove the ignition coils by unscrewing them (if applicable) and gently pull them out.
Use a spark plug socket to remove the spark plugs from the cylinder head.
Inspect the old plugs for signs of wear or fouling; replace with new spark plugs to manufacturer specifications (typically around 0.044 inches for gap).
Reinstall the ignition coils and ensure they are firmly seated.

4. Check and Replace Air Filter

Locate the air filter housing and unclip the cover.
Remove the old air filter and inspect the housing for dirt and debris.
Install a new air filter, ensuring it fits snugly in its housing.

5. Test Fuel Injectors

Connect a fuel pressure gauge to the fuel rail and start the engine.
Monitor the fuel pressure while idling; it should be within specifications (usually around 30-40 PSI, but check the service manual for exact readings).
If pressure is low, consider cleaning or replacing the fuel injectors.

6. Inspect for Vacuum Leaks

Visually inspect hoses connected to the intake manifold for cracks or disconnections.
Use a smoke machine or spray carb cleaner around the intake area while the engine is running; if the idle changes, you have found a leak.
Replace or repair any damaged hoses or gaskets.
