Solution

1. Preparation

Ensure the vehicle is in a safe, flat location and turn off the ignition.
Disconnect the negative battery terminal to prevent electrical shorts.
Gather essential tools including a socket set, OBD-II scanner, and multimeter.

2. Fuel System Inspection

Step 1: Inspect the fuel pump and ensure it is functioning.
- Tools Required: Fuel pressure gauge.
- Connect the fuel pressure gauge to the fuel rail and turn the ignition to the "ON" position without starting the engine to check pressure.
- Normal pressure should be within manufacturer specifications; if low, consider replacing the fuel pump.
Step 2: Check fuel injectors for clogs or failure.
- Remove injectors and test their spray pattern with a fuel injector cleaner.
- Clean or replace any faulty injectors as necessary.

3. Ignition System Repair

Step 1: Replace worn spark plugs.
- Remove the ignition coils and spark plugs using a socket wrench.
- Inspect for wear; replace with OEM specifications if necessary, and torque to manufacturer's specifications.
Step 2: Test and replace ignition coils if required.
- Use a multimeter to test the resistance of each coil.
- Replace any coils showing out-of-spec resistance.

4. Air Intake and Throttle Body Cleaning

Step 1: Remove the throttle body for inspection.
- Disconnect the throttle body electrical connector and remove the bolts securing it.
- Clean the throttle plate and body using throttle body cleaner.
Step 2: Inspect and clean the MAF sensor.
- Remove the MAF sensor and spray it with MAF cleaner to remove dirt and debris.
