Solution

1. Preparation

Gather tools and parts.
Disconnect the negative battery terminal to ensure safety.
Allow the engine to cool down before starting work.

2. Address Fuel System Issues

Tools Required: Fuel pressure gauge, wrenches
Sub-steps:
1. Connect the fuel pressure gauge to the fuel rail service port.
2. Turn the ignition to the ON position (do not start the engine) and check the pressure reading.
3. If the pressure is below specifications (usually around 55-65 psi), inspect and replace the fuel pump if necessary.
4. Check the fuel filter for clogs and replace if needed.

3. Clean or Replace Throttle Body

Tools Required: Socket set, throttle body cleaner, rags
Sub-steps:
1. Remove the air intake duct to access the throttle body.
2. Disconnect the throttle body electrical connector.
3. Remove the throttle body mounting bolts and take it off the intake manifold.
4. Clean the throttle body with throttle body cleaner and a rag.
5. If damaged, replace with a new throttle body and reinstall.

4. Inspect and Replace Ignition Components

Tools Required: Socket set, torque wrench
Sub-steps:
1. Remove the ignition coils by disconnecting the electrical connectors and unscrewing the bolts.
2. Inspect spark plugs for wear; replace if necessary (should be gapped correctly).
3. Reinstall new or cleaned ignition coils with proper torque specifications.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the engine and allow it to idle.
Check for any error codes using an OBD-II scanner and clear them if necessary.
