Solution

1. Preparation

Ensure the vehicle is parked on a flat surface.
Disconnect the negative terminal of the battery to prevent electrical shorts.
Gather necessary tools and replacement parts.

2. Inspect and Replace Ignition Components

Tools Required: Socket set, torque wrench, ignition coil puller.
Remove any engine covers to access the ignition system.
Disconnect the electrical connectors from the ignition coils and remove them from the spark plugs.
Inspect the spark plugs for wear; replace if necessary with OEM parts.
Reinstall the ignition coils, ensuring they are properly seated and connected.

3. Fuel System Inspection

Tools Required: Fuel pressure gauge, wrench set.
Check the fuel pump fuse and relay; replace if faulty.
Using the fuel pressure gauge, connect it to the fuel rail and turn the ignition on to measure fuel pressure.
If pressure is low, inspect the fuel pump and fuel filter for blockages; replace as needed.
Reconnect all components and ensure no leaks are present.

4. Air Intake and MAF Sensor Cleaning

Tools Required: Screwdriver set, cleaning spray for MAF sensors.
Locate the air intake duct and remove it from the throttle body.
Inspect the air filter; replace if dirty.
Clean the mass airflow sensor with appropriate cleaner and reinstall the air intake duct.

5. Final Assembly

Reconnect the battery terminal.
Start the engine and check for smooth operation and any warning lights.
Ensure all tools are removed from the engine bay.
