Solution

1. Preparation

Gather tools: OBD-II scanner, fuel pressure gauge, socket set, torque wrench, cleaning supplies, and safety equipment (gloves, goggles).
Disconnect the negative battery terminal to ensure safety during repairs.

2. Address Air Intake Issues

Remove the air intake duct by loosening the clamps and disconnecting any sensors.
Inspect and replace the air filter if dirty.
Clean the throttle body using throttle body cleaner and a soft cloth.
Reassemble the air intake duct and reconnect sensors.

3. Fuel System Inspection

Connect the fuel pressure gauge to the fuel rail's Schrader valve.
Turn the ignition to the "ON" position (do not start the engine) to check fuel pressure.
If pressure is below specifications, check the fuel pump and relay. Replace if necessary.
Clean or replace fuel injectors if they are clogged.

4. Ignition System Repair

Remove spark plugs using a socket wrench and inspect for wear or carbon deposits.
Replace spark plugs if they appear worn or fouled, ensuring to torque them to manufacturer specifications.
Inspect ignition coils for cracks or damage and replace as necessary.

5. Final Checks

Reconnect the battery terminal.
Start the engine and check for smooth operation during acceleration.
Clear any diagnostic trouble codes using the OBD-II scanner.
