Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety.
Allow the engine to cool before beginning work.

2. Inspect and Clean Air Intake

Remove the air intake duct to access the air filter.
Inspect and replace the air filter if dirty. Ensure it is seated properly.
Clean the throttle body using throttle body cleaner and a soft cloth.

3. Check Fuel System

Connect a fuel pressure gauge to the fuel rail.
Turn the ignition to the "On" position (do not start the engine) and check the fuel pressure.
- If the pressure is below specifications, check the fuel pump and filter.
Replace the fuel filter if clogged.

4. Examine Ignition System

Remove spark plug wires or ignition coils.
Inspect spark plugs for wear or fouling and replace if necessary.
Test ignition coils with a multimeter to ensure they are within specifications; replace defective coils.

5. Inspect Exhaust System

Visually inspect the exhaust system for any visible damage or blockages.
If equipped, check the catalytic converter for signs of clogging or failure.

6. Electrical System Check

Use a multimeter to test the battery voltage; it should read between 12.4 to 12.7 volts when the engine is off.
Start the engine and check the voltage again; it should read between 13.7 to 14.7 volts to confirm the alternator is functioning properly.
Replace the battery or alternator if readings are outside these ranges.
