Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the battery (negative terminal) to ensure safety during the repair.

2. Replace Air Filter

Remove the air filter cover using a socket set.
Take out the old air filter and inspect the housing for debris. Clean if necessary.
Install the new air filter and reassemble the air filter cover.

3. Inspect and Replace Spark Plugs

Remove the ignition coil connectors and unscrew the coils from the engine.
Use a spark plug socket to remove the old spark plugs.
Inspect the plugs for wear; replace with new plugs if necessary (use correct gap specifications).
Reinstall the new spark plugs and ignition coils, ensuring proper torque is applied.

4. Fuel System Check

Attach a fuel pressure gauge to the fuel rail.
Turn the ignition to the "On" position (without starting the engine) to check the pressure.
If pressure is below specifications, replace the fuel filter or fuel pump as necessary.

5. Vacuum Leak Inspection

Visually inspect all vacuum lines for cracks or disconnections.
Use a smoke machine or carburetor cleaner to check for leaks while the engine is running.
Replace any damaged vacuum lines identified during the inspection.

6. Exhaust System Inspection

Inspect the exhaust system for any signs of blockage or damage.
If a clogged catalytic converter is suspected, perform a backpressure test to confirm.
Replace the catalytic converter if necessary following manufacturer specifications.
