Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety.

2. Inspect and Replace Spark Plugs

Sub-steps:
1. Remove the engine cover if applicable.
2. Disconnect ignition coils from each spark plug.
3. Use a spark plug socket to remove the old spark plugs.
4. Inspect the old plugs for wear; replace with new plugs if necessary (Torque to manufacturer specifications, typically around 15-20 lb-ft).
5. Reinstall ignition coils and engine cover.

3. Check and Clean Air Intake System

Sub-steps:
1. Remove the air intake duct.
2. Inspect the air filter; replace if dirty.
3. Clean the throttle body using throttle body cleaner and a soft cloth.
4. Reassemble the air intake duct securely.

4. Fuel System Inspection

Sub-steps:
1. Remove the fuel pump relay to relieve pressure in the fuel system.
2. Inspect the fuel filter; replace if clogged.
3. Test the fuel pump operation by checking the pressure at the fuel rail (should be within manufacturer specifications, typically around 58-65 psi).
4. Reinstall the fuel pump relay after inspection.

5. Battery and Charging System Check

Sub-steps:
1. Use a multimeter to check battery voltage; it should read around 12.6 volts when fully charged.
2. Start the vehicle and check voltage again; it should read between 13.7 and 14.7 volts.
3. Replace the battery or alternator if readings are outside of this range.
