Solution

1. Preparation

Tools Required: OBD-II scanner, fuel pressure gauge, socket set, multimeter, cleaning solvent.
Disconnect the battery to ensure safety before working on electrical components.

2. Clean or Replace Air Filter

Remove the air filter cover using a socket set.
Take out the air filter and inspect it for dirt; replace if necessary.
Clean the air filter housing with a cleaning solvent if dirt is present.

3. Throttle Body Cleaning

Locate the throttle body, usually positioned between the air intake and the intake manifold.
Disconnect the throttle body electrical connector and vacuum lines.
Use a throttle body cleaner and a soft cloth to clean the throttle plate and housing.
Reassemble the throttle body and reconnect the electrical connector.

4. Inspect and Replace Fuel Filter (if needed)

Identify the fuel filter location, usually near the fuel tank or along the fuel line.
Relieve fuel system pressure before disconnecting the fuel lines.
Replace the fuel filter with a new one, ensuring proper alignment and secure connections.

5. Spark Plug and Ignition Coil Inspection

Remove the ignition coil covers (if applicable) using a socket set.
Take out the ignition coils and inspect them for cracks or damage.
Check spark plugs for wear; replace them if they are worn or fouled.
