Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety before starting repairs.

2. Fuel System Inspection

Sub-steps:
1. Remove the fuel pump relay from the fuse box.
2. Disconnect the fuel line from the fuel rail using a wrench.
3. Install a fuel pressure gauge to check pressure readings against manufacturer specifications (typically 40-50 PSI).
4. Replace fuel filter if it is clogged.
5. If pressure is low, replace the fuel pump.

3. Ignition System Repair

Sub-steps:
1. Remove the spark plug wires and inspect for wear or damage.
2. Use a spark plug socket to remove the spark plugs; inspect for fouling or wear.
3. Replace any faulty spark plugs with OEM equivalents.
4. Test ignition coils with a multimeter; replace if the resistance is outside specifications.

4. Air Intake System Check

Sub-steps:
1. Remove the air intake duct to access the mass airflow sensor (MAF).
2. Clean the MAF sensor using MAF cleaner spray.
3. Inspect the air filter; replace if dirty or clogged.
4. Reassemble the air intake system.

5. Electrical System Assessment

Sub-steps:
1. Check battery voltage with a multimeter; replace the battery if voltage is below 12.4 volts.
2. Inspect the alternator's output while the engine is running; it should be around 13.5-14.5 volts.
3. Replace any corroded or loose battery terminals as needed.
