Solution

1. Preparation

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

2. Clean or Replace Air Filter

Remove the air filter housing cover using a socket set.
Take out the air filter and inspect it for dirt and blockages.
If dirty, replace the air filter with a new OEM part.
Reinstall the air filter housing cover and ensure it is securely fastened.

3. Fuel Pressure Check

Connect the fuel pressure gauge to the Schrader valve on the fuel rail.
Turn the ignition key to the "ON" position (without starting the engine) to check the pressure.
Compare the reading with the manufacturer specifications (typically around 30-45 psi).
If pressure is low, inspect the fuel pump and filter for issues, and replace if necessary.

4. Throttle Body Cleaning

Remove the throttle body from the intake manifold by unscrewing the bolts.
Use throttle body cleaner and a soft cloth to remove carbon buildup.
Reinstall the throttle body and reconnect the electrical connector and vacuum lines.

5. Inspect and Replace Ignition Components

Remove the ignition coil cover and disconnect the ignition coils.
Inspect spark plugs for wear and replace if they appear fouled or worn.
Replace any damaged ignition wires and ensure proper connections are made.

6. Vacuum Hose Inspection

Visually inspect all vacuum hoses for cracks, tears, or disconnections.
Replace any damaged hoses with OEM replacements.
