Solution

1. Preparation

Gather tools and parts needed for repair.
Disconnect the negative terminal of the battery to ensure safety.

2. Clean or Replace Air Filter

Remove the air intake duct by loosening the clamps and disconnecting any attached sensors.
Inspect the air filter for dirt and debris.
If dirty, replace it with a new OEM filter. If reusable, clean it according to manufacturer specifications.

3. Throttle Body Cleaning

Locate and remove the throttle body by unscrewing the mounting bolts.
Use throttle body cleaner and a soft brush to remove carbon deposits.
Reattach the throttle body and ensure all connections are secure.

4. Fuel System Check

If fuel pressure is low, replace the fuel filter and inspect the fuel pump for proper operation.
Ensure the fuel lines are free from kinks or leaks.

5. Ignition System Repair

Remove the spark plugs using a socket wrench and inspect them for wear or fouling.
Replace worn or damaged spark plugs with new ones, ensuring the correct gap is set.
Test and replace ignition coils if necessary.

6. Exhaust System Inspection

Check for any visible signs of damage or blockage in the exhaust system.
If the catalytic converter is suspected to be clogged, consider replacing it with a new one.
