Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, vacuum gauge, cleaning supplies.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the negative battery terminal to prevent accidental electrical shorts.

2. Replace Engine Mounts

Sub-steps:
1. Lift the Vehicle: Use a jack and jack stands to elevate the vehicle safely.
2. Remove Undertray (if present): Unscrew any fasteners that hold the undertray in place.
3. Support the Engine: Place a jack under the oil pan with a block of wood to distribute weight evenly.
4. Remove Old Mounts: Use a socket set to remove bolts securing the engine mounts to the engine and chassis.
5. Install New Mounts: Position new engine mounts and torque the bolts to the manufacturer's specifications (consult repair manual for specific torque values).

3. Clean or Replace Spark Plugs

Sub-steps:
1. Remove Ignition Coils: Disconnect the electrical connectors and unscrew the coils.
2. Check Spark Plugs: Inspect for wear and deposits; replace if necessary.
3. Install New Spark Plugs: Torque to the specified value (usually around 20 Nm but verify with the repair manual).

4. Clean MAF Sensor

Sub-steps:
1. Remove MAF Sensor: Disconnect the electrical connector and unscrew the sensor from the intake.
2. Clean Sensor: Use MAF cleaner spray to clean the sensor element; avoid touching it directly.
3. Reinstall MAF Sensor: Secure it back in place and reconnect the electrical connector.
