Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace Spark Plugs

Sub-steps:
- Remove the ignition coil covers if applicable.
- Use a spark plug socket to remove the spark plugs.
- Inspect the spark plugs for wear or fouling; replace if necessary.
- Gap the new spark plugs according to manufacturer specifications.
- Reinstall the spark plugs and ignition coil covers.

3. Test and Replace Ignition Coils (if necessary)

Sub-steps:
- Use a multimeter to test the resistance of each ignition coil.
- If any coils are out of specification, remove and replace them.
- Reconnect the electrical connectors to the new coils.

4. Fuel System Inspection

Sub-steps:
- Inspect the fuel filter and replace it if clogged or old.
- Check the fuel lines for leaks or obstructions.
- Test the fuel pressure using a fuel pressure gauge; ensure it meets specifications.
- Replace the fuel pump if the pressure is low and it does not operate correctly.

5. Air Intake and Sensors Check

Sub-steps:
- Inspect the air filter; replace it if dirty or clogged.
- Check the Mass Airflow Sensor (MAF) and clean it with appropriate MAF cleaner if contaminated.
- Inspect Vacuum hoses for leaks and replace any damaged hoses.
