Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Clean Air Filter

Remove the air filter housing cover using a socket set.
Take out the air filter and inspect it for dirt and blockages.
Clean or replace the air filter as necessary.
Reinstall the air filter and housing cover securely.

3. Check and Replace Spark Plugs

Remove ignition coils using a socket set.
Take out the old spark plugs with a spark plug socket.
Inspect the spark plugs for wear; replace if they appear worn or fouled.
Install new spark plugs and torque them to manufacturer specifications (typically around 13-15 ft-lbs).
Reinstall the ignition coils.

4. Clean Throttle Body

Remove the intake duct connected to the throttle body.
Spray throttle body cleaner onto a clean cloth and wipe the throttle body’s interior.
Ensure the throttle plate opens and closes smoothly.
Reassemble the intake duct securely.

5. Fuel System Inspection

Connect a fuel pressure gauge to the fuel rail.
Start the engine and monitor fuel pressure; it should meet manufacturer specifications (usually around 43-50 psi depending on the engine).
If pressure is low, check the fuel pump and filter for issues and replace if necessary.
