Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is turned off.
Gather necessary tools and safety equipment.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Clean the Throttle Body

Tools Required: Throttle body cleaner, screwdriver set, cleaning cloth.
Remove the air intake duct from the throttle body.
Spray throttle body cleaner onto a cloth and wipe the inside of the throttle body to remove carbon deposits.
Open the throttle plate manually and clean it thoroughly.
Reattach the air intake duct securely.

3. Replace Spark Plugs

Tools Required: Socket set, torque wrench.
Remove the ignition coil covers (if applicable).
Disconnect the ignition coils and remove them from the spark plugs.
Use a socket to remove the old spark plugs and inspect the condition.
Install new spark plugs, ensuring to torque them to the manufacturer’s specifications (typically 13-15 lb-ft).
Reconnect the ignition coils and covers.

4. Check Battery and Electrical Connections

Tools Required: Multimeter.
Measure the battery voltage; it should be around 12.6 volts when fully charged.
Inspect battery terminals for corrosion and ensure they are tight. Clean them if necessary.
Check ground connections for any signs of damage or corrosion.

5. Inspect Fuel System

Tools Required: Fuel pressure gauge.
Attach the fuel pressure gauge to the fuel rail's test port.
Turn the ignition to the ON position (without starting the engine) and check the fuel pressure reading against specifications.
If pressure is low, inspect the fuel pump, fuel filter, and fuel lines for clogs or leaks.
