Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical systems.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.

2. Air Filter Replacement

Remove the air intake duct to access the air filter.
Take out the old air filter and check for significant dirt or damage.
Install a new, clean air filter.
Reassemble the air intake duct.

3. Fuel System Inspection

Use a fuel pressure gauge to check the fuel pressure at the fuel rail.
If pressure is low, replace the fuel filter and inspect the fuel pump.
Reconnect any components and check for fuel leaks.

4. Throttle Body Cleaning

Locate the throttle body and remove the intake hose.
Use throttle body cleaner and a soft brush to clean the throttle plate and inside of the throttle body.
Reattach the intake hose securely.

5. Ignition System Check

Remove spark plugs and inspect for wear or fouling.
Replace any worn or damaged spark plugs with new ones, ensuring the proper gap is set.
Test ignition coils with a multimeter for resistance; replace any that are out of spec.

6. Exhaust System Check

Inspect the exhaust system visually for any damage, leaks, or blockages.
If the catalytic converter is suspected to be clogged, consider replacing it.
