Solution

1. Preparation

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

2. Inspect Fuel System

Sub-steps:
1. Locate the fuel pump access point (usually under the rear seat or in the trunk).
2. Use a fuel pressure gauge to check the fuel pump pressure; it should meet manufacturer specifications.
3. Replace the fuel filter if it’s clogged or has not been replaced per maintenance schedule.
4. If fuel pressure is low, replace the fuel pump.

3. Clean or Replace Throttle Body

Sub-steps:
1. Remove the intake duct to access the throttle body.
2. Clean the throttle body using throttle body cleaner and a soft cloth.
3. Inspect the throttle position sensor and replace it if faulty.
4. Reconnect the intake duct.

4. Replace Spark Plugs and Ignition Coils

Sub-steps:
1. Remove the engine cover to access the spark plugs.
2. Disconnect the ignition coils and remove them.
3. Extract old spark plugs using a spark plug socket.
4. Install new spark plugs, ensuring they are gapped according to manufacturer specifications (typically around 0.028-0.032 inches).
5. Reinstall ignition coils and reconnect wiring.

5. Test and Replace MAF Sensor

Sub-steps:
1. Locate the mass airflow sensor in the intake duct.
2. Disconnect the electrical connector and remove the sensor.
3. Clean the MAF sensor with MAF cleaner (do not touch the sensor element).
4. If cleaning does not resolve issues, replace the MAF sensor with a new unit.
