Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative terminal of the battery for safety.

2. Throttle Body Cleaning

Remove the intake duct by loosening the hose clamps and disconnecting any associated sensors.
Access the throttle body; remove the mounting screws using a socket set.
Clean the throttle body using throttle body cleaner and a soft cloth, ensuring no cleaner enters the throttle plate.
Reinstall the throttle body and intake duct, tightening screws to manufacturer specifications.

3. Fuel System Inspection

Attach the fuel pressure gauge to the fuel rail test port.
Start the engine and monitor the fuel pressure; it should meet manufacturer specifications.
If pressure is low, inspect the fuel pump and filter for obstructions or failures, replacing as necessary.

4. Spark Plug Inspection

Remove the spark plug wires carefully to avoid damage.
Use a spark plug socket to remove the spark plugs.
Inspect each spark plug for signs of wear or fouling; replace if necessary.
Reinstall new spark plugs, ensuring they are torqued to the manufacturer’s specifications.

5. Battery and Charging System Check

Inspect battery terminals for corrosion and ensure they are tight.
Use a multimeter to check the battery voltage; it should read between 12.4 and 12.7 volts when the engine is off.
If the voltage is low, consider charging the battery or replacing it.
