Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety during repairs.
Allow the engine to cool before starting work.

2. Replace Air Filter

Locate the air filter housing, usually near the front of the engine bay.
Open the housing by releasing the clips or screws.
Remove the old air filter and replace it with a new one.
Reassemble the housing and ensure it is securely closed.

3. Fuel System Inspection

Remove the fuel pump relay from the fuse box.
Connect a fuel pressure gauge to the fuel rail service port.
Turn on the ignition without starting the engine to check pressure; it should match the specifications in the repair manual (typically around 30-60 psi).
If pressure is low, consider replacing the fuel filter or fuel pump.

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 body interior.
Ensure that the throttle plate moves freely; if not, replace the throttle body.

5. Inspect and Replace Ignition Components

Remove the spark plug wires and inspect for wear or damage.
Test spark plugs for wear; replace if the electrode is worn or if they are fouled.
Replace ignition coils if they show signs of failure (cracks, corrosion).

6. Exhaust System Check

Visually inspect the exhaust system for any signs of blockage or damage.
If a blockage is suspected, remove the affected section of the exhaust and check for obstructions.
