Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to prevent electrical shorts.
Allow the engine to cool down before starting work.

2. Replace Air Filter

Remove the air filter cover using a socket set.
Take out the old air filter and inspect the housing for debris.
Install a new air filter, ensuring it fits securely.
Reattach the air filter cover and tighten to specifications.

3. Check and Replace Spark Plugs

Remove the ignition coil or wire from the spark plugs.
Use a socket wrench to remove the old spark plugs.
Inspect the old plugs; replace if worn or fouled.
Install new spark plugs, torquing to manufacturer specifications (typically 13-15 lb-ft).
Reconnect the ignition coil or wire.

4. Clean Throttle Body

Remove the intake duct connected to the throttle body.
Use throttle body cleaner and a soft brush to clean the throttle plate and surrounding areas.
Reattach the intake duct securely.

5. Test Fuel Pressure

Connect a fuel pressure gauge to the fuel rail.
Start the engine and observe the pressure readings; compare with manufacturer specifications.
If pressure is low, consider replacing the fuel pump.
