Solution

1. Preparation

Gather necessary tools and components.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Clean Air Intake

Tools Needed: Socket set, cleaning solvent, soft cloth
Remove the air intake duct to access the air filter.
Inspect the air filter for dirt and replace it if necessary.
Clean the air intake duct using a cleaning solvent and a soft cloth to remove any debris.

3. Test and Replace Fuel Filter

Tools Needed: Fuel pressure gauge, wrench set
Connect the fuel pressure gauge to the fuel rail.
Turn the ignition key to the "On" position (do not start) and check the pressure reading against manufacturer specifications.
If the fuel pressure is low, locate the fuel filter and replace it following the manufacturer’s guidelines.

4. Clean or Replace Throttle Body

Tools Needed: Throttle body cleaner, socket set
Remove the throttle body from the intake manifold.
Use throttle body cleaner to clean the inside surfaces thoroughly.
Reinstall the throttle body, ensuring all gaskets are in good condition and properly seated.

5. Test and Replace Spark Plugs and Coils

Tools Needed: Spark plug socket, torque wrench
Remove the spark plugs and inspect them for wear or carbon buildup.
Replace any worn spark plugs with new ones, ensuring proper gap settings per manufacturer specifications.
If necessary, replace ignition coils by removing and installing new coils on each cylinder.
