Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on the vehicle.

2. Address Error Codes

Sub-step 1: Use the OBD-II scanner to retrieve error codes.
Sub-step 2: Reference the error codes against a repair manual to determine the specific issue.
Tools Required: OBD-II scanner

3. Inspect and Clean Throttle Body

Sub-step 1: Remove the air intake duct connected to the throttle body.
Sub-step 2: Remove the throttle body from the intake manifold (torque specifications: 89 in-lbs).
Sub-step 3: Clean the throttle body using throttle body cleaner and a soft cloth.
Sub-step 4: Reinstall the throttle body and reconnect the air intake duct.
Tools Required: Socket set, throttle body cleaner

4. Check and Replace Ignition Components

Sub-step 1: Remove the ignition coils from the spark plugs.
Sub-step 2: Inspect the spark plugs for wear; replace if necessary (gapping specification: 0.054 in).
Sub-step 3: Test the ignition coils with a multimeter for proper resistance.
Sub-step 4: Reinstall or replace components as necessary.
Tools Required: Socket set, multimeter

5. Fuel System Inspection

Sub-step 1: Attach a fuel pressure gauge to the fuel rail.
Sub-step 2: Start the engine and check for fuel pressure (specification: approximately 55-65 psi).
Sub-step 3: If pressure is low, inspect the fuel pump and fuel filter for blockages.
Sub-step 4: Replace the fuel filter if necessary.
Tools Required: Fuel pressure gauge, socket set
