Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative terminal of the battery to ensure safety during repairs.

2. Address Fuel System Issues

Inspect the Fuel Pump:
- Remove the fuel pump access panel (if applicable).
- Use a fuel pressure gauge to check the pump's pressure; it should meet manufacturer specifications (typically around 50-60 psi).
- If pressure is low, replace the fuel pump.
Replace the Fuel Filter:
- Locate the fuel filter (usually near the fuel tank or along the fuel line).
- Disconnect the fuel lines (use caution due to potential fuel spillage).
- Replace the old filter with a new one, ensuring proper orientation.

3. Check and Replace Ignition Components

Inspect Spark Plugs:
- Remove spark plug wires and use a socket to extract the spark plugs.
- Check for wear or carbon buildup; replace if necessary (use OEM parts).
- Reinstall the new spark plugs with a torque value of 13 lb-ft.
Inspect Ignition Coils:
- Remove ignition coils and check for cracks or corrosion.
- Replace any faulty coils with new ones.

4. Inspect and Clean Air Intake System

Clean the MAF Sensor:
- Disconnect the MAF sensor connector.
- Use a MAF cleaner spray to carefully clean the sensor element.
- Reconnect the sensor once dry.
Replace Air Filter:
- Open the air filter housing and remove the old air filter.
- Install a new, clean air filter.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the engine and allow it to idle, checking for any irregularities.
