Solution

1. Preparation

Tools Required: OBD-II scanner, fuel pressure gauge, socket set, torque wrench, cleaning supplies, multimeter.
Safety Warnings: Disconnect the battery before working on electrical systems and allow the engine to cool before opening any components.

2. Fuel System Inspection

Use the fuel pressure gauge to check fuel pressure against manufacturer specifications.
If pressure is low, inspect the fuel pump, fuel filter, and lines for blockages or failures.
Replace the fuel filter if necessary.

3. Air Intake Cleaning

Remove the air filter and inspect it for dirt and obstructions.
Clean or replace the air filter if it is dirty.
Remove the throttle body and clean it with throttle body cleaner to remove carbon buildup.

4. Ignition System Check

Remove the spark plugs and inspect for wear or deposits.
Replace spark plugs if they show signs of wear.
Test ignition coils using a multimeter to ensure they are within specifications; replace any faulty coils.

5. Addressing Vacuum Leaks

Inspect all vacuum hoses for cracks or disconnections.
Replace any damaged hoses.
Check the intake manifold for leaks using a smoke machine or by spraying carburetor cleaner around the base while the engine runs.
