Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to avoid electrical issues during service.

2. Inspect and Clean Throttle Body

Sub-steps:
1. Remove the air intake duct connected to the throttle body using a socket set.
2. Disconnect the throttle position sensor connector.
3. Use throttle body cleaner and a soft brush to clean the throttle plate and body.
4. Reconnect the throttle position sensor and reinstall the air intake duct.

3. Check and Replace Air Filter (if necessary)

Sub-steps:
1. Locate the air filter housing and unclip or unscrew it.
2. Remove the old air filter and inspect for dirt or damage.
3. Install a new, clean air filter into the housing.
4. Reassemble the air filter housing.

4. Fuel Pressure Test and Repair

Sub-steps:
1. Locate the fuel rail and attach the fuel pressure gauge.
2. Turn the ignition to the "ON" position (do not start the engine) to check pressure reading.
3. If pressure is low, inspect the fuel pump and filter for issues.
4. Replace the fuel filter if clogged, and consider replacing the fuel pump if it fails to meet specifications.

5. Inspect and Replace Ignition Components (if needed)

Sub-steps:
1. Remove the engine cover to access the ignition coils.
2. Check the condition of each spark plug and coil.
3. Replace any damaged or worn plugs and coils with OEM components.
4. Reinstall the engine cover.
