Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the battery to prevent electrical shocks.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.

2. Fuel System Inspection

Remove the fuel pump access panel (if applicable) or disconnect the fuel lines.
Tools Required: Fuel pressure gauge, wrench set, safety goggles.
Check the fuel pressure using a gauge; it should meet the specifications for the model.
Replace the fuel filter if clogged or if it's been over the manufacturer's recommended service interval.

3. Ignition System Repair

Remove spark plug wires and inspect spark plugs for wear or fouling.
Tools Required: Spark plug socket, torque wrench.
Replace any worn spark plugs with OEM parts, ensuring proper gap settings.
Test ignition coils with a multimeter to ensure they are within specifications and replace if faulty.

4. Air Intake System Check

Inspect the air filter and replace if dirty or clogged.
Tools Required: Screwdriver or pliers (for clamps).
Check for any cracks or disconnections in the intake hoses.
Clean the throttle body using an appropriate cleaner and a soft cloth.

5. Vacuum Leak Inspection

Use a smoke machine or carburetor cleaner to identify vacuum leaks around hoses and intake manifold.
Replace any damaged or cracked hoses.
