Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, fuel pressure gauge, multimeter, basic hand tools.
Disconnect the battery to prevent electrical issues while working on the vehicle.

2. Replace Spark Plugs and Ignition Coils

Sub-steps:
1. Remove the engine cover if applicable to access the ignition components.
2. Disconnect the ignition coil connectors and remove the coils using a socket set.
3. Remove the old spark plugs using a spark plug socket and inspect for wear.
4. Install new spark plugs, ensuring correct torque (typically 13-16 lb-ft).
5. Reinstall the ignition coils and reconnect the connectors.

3. Inspect and Clean Fuel Injectors

Sub-steps:
1. Disconnect the fuel pump relay and relieve fuel system pressure.
2. Remove the fuel rail bolts and gently pull the fuel rail with injectors off the engine.
3. Inspect the fuel injectors for clogs or damage; clean them using a fuel injector cleaner or replace them if necessary.
4. Reassemble the fuel rail and reconnect all components.

4. Check and Clean Air Intake System

Sub-steps:
1. Remove the air filter and inspect for dirt or blockages; replace if needed.
2. Check the intake ducts for leaks or cracks.
3. Clean the throttle body using throttle body cleaner.
4. Reassemble the air intake system ensuring all connections are secure.

5. Inspect Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick and check fluid level with the engine running.
2. If the fluid is low, add the manufacturer's recommended transmission fluid.
3. If fluid is dirty or smells burnt, consider a transmission fluid change.
