Solution

1. Preparation

Gather tools and park the vehicle on a level surface.
Disconnect the battery to prevent any electrical issues.
Tools required: OBD-II scanner, fuel pressure gauge, socket set, multimeter, cleaning supplies.

2. Inspect and Replace the Air Filter

Remove the air filter housing cover by unscrewing any fasteners.
Take out the air filter and inspect it for dirt or damage.
Replace with a new air filter if clogged or damaged.
Reassemble the air filter housing.

3. Fuel System Check

Attach the fuel pressure gauge to the fuel rail.
Turn the ignition to the "On" position without starting the engine to check the fuel pressure.
Compare the reading with the manufacturer's specifications; if low, check the fuel pump and fuel filter.
If necessary, replace the fuel filter or pump.

4. Throttle Body Cleaning

Remove the throttle body from the intake manifold by disconnecting any electrical connectors and vacuum hoses.
Clean the throttle body using throttle body cleaner and a soft cloth.
Reinstall the throttle body and reconnect all hoses and connectors.

5. Inspect and Replace Ignition Components

Remove the ignition coil cover and check the spark plugs for wear.
Replace any worn plugs with new ones, ensuring the gap is set to manufacturer specifications.
If ignition coils show signs of failure, replace as necessary.

6. Exhaust System Inspection

Check for any visible damage or blockages in the exhaust system.
If the catalytic converter is suspected to be clogged, consider replacing it.
Reassemble any components that were removed during inspection.
