Solution

1. Preparation

Gather tools and parts.
Disconnect the negative battery terminal to prevent electrical issues.

2. Inspect and Clean Air Intake System

Remove the air intake duct.
Inspect the air filter for dirt and replace if necessary.
Clean the intake manifold and throttle body with a suitable cleaner.
Reassemble the air intake components securely.

3. Check Fuel System

Install a fuel pressure gauge on the fuel rail.
Start the engine and check the fuel pressure readings against manufacturer specifications (typically around 30-50 psi for most engines).
If pressure is low, inspect the fuel pump and filter; replace if faulty.

4. Examine Ignition System

Remove the spark plugs and check for wear or fouling.
Replace spark plugs if they show signs of excessive wear or carbon buildup.
Test ignition coils with a multimeter and replace any that are out of specification.

5. Inspect Battery and Charging System

Use a multimeter to check battery voltage (should be around 12.6 volts when not running and 13.7-14.7 volts when running).
Clean battery terminals and connections.
Replace the battery if it fails to hold a charge.
