Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and set the parking brake.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Air Filter Inspection and Replacement

Remove the air intake duct to access the air filter.
Inspect the air filter for dirt and debris.
Replace the air filter if it is dirty or clogged.
Reassemble the air intake duct and reconnect the battery.

3. Fuel System Inspection and Repair

Use a fuel pressure gauge to measure fuel pressure at the fuel rail.
If pressure is low, inspect the fuel pump and fuel filter for issues. Replace if necessary.
Check fuel injectors for proper operation; clean or replace if clogged.

4. Throttle Body Cleaning

Remove the throttle body from the intake manifold.
Use throttle body cleaner and a soft cloth to remove carbon buildup.
Reinstall the throttle body and ensure all connections are secure.

5. Ignition System Maintenance

Remove spark plugs and inspect for wear or fouling.
Replace spark plugs with OEM specifications if necessary.
Test ignition coils for proper operation using a multimeter and replace if faulty.

6. Exhaust System Check

Inspect the exhaust system visually for any leaks or damage.
If a clogged catalytic converter is suspected, perform a backpressure test and replace it if necessary.
