Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety during the repair process.

2. Fuel System Inspection

Sub-steps:
1. Remove the fuel pump relay and turn the ignition key to the "ON" position to relieve fuel pressure.
2. Inspect the fuel filter for clogs; replace if necessary.
3. Reconnect the fuel pump relay and check fuel pump operation by turning the ignition to the "ON" position and listening for the pump's sound.
4. If fuel pressure is low, replace the fuel pump as needed.

3. Ignition System Repair

Sub-steps:
1. Remove the engine cover (if applicable) to access ignition components.
2. Inspect spark plugs for wear; replace if the electrodes are worn or if there is excessive carbon build-up.
3. Test ignition coils using a multimeter to check for proper resistance; replace any faulty coils.

4. Air Intake Inspection

Sub-steps:
1. Disconnect the air intake duct from the throttle body.
2. Inspect the air filter for dirt or clogs; replace if necessary.
3. Check for vacuum leaks in hoses and at connections; repair or replace any damaged components.
4. Clean the throttle body using throttle body cleaner to ensure smooth operation.
