Solution

1. Preparation

Gather necessary tools and parts. Ensure you are in a well-ventilated area.
Tools Required: OBD-II scanner, socket set, multimeter, throttle body cleaner, torque wrench, basic hand tools.
Safety Warnings: Disconnect the battery before working on electrical systems. Allow the engine to cool before performing any inspections.

2. Address Fuel Issues

Step 1: If fuel contamination is suspected, drain the fuel tank using a siphon pump.
Step 2: Replace contaminated fuel with high-quality fuel.
Step 3: Replace the fuel filter if it shows signs of clogging.

3. Inspect and Clean Throttle Body

Step 1: Remove the air intake duct connected to the throttle body using a socket set.
Step 2: Disconnect the throttle body electrical connector.
Step 3: Remove the throttle body from the intake manifold, noting the orientation.
Step 4: Clean the throttle plate and bore with throttle body cleaner and a soft cloth.
Step 5: Reinstall the throttle body and reconnect the electrical connector and air intake duct.

4. Check Ignition System

Step 1: Remove spark plugs using a socket set and inspect for wear or deposits.
Step 2: Replace any worn or damaged spark plugs with OEM parts.
Step 3: Test each ignition coil for proper resistance using a multimeter; replace faulty coils.

5. Verify Electrical Supply

Step 1: Use a multimeter to test the battery voltage; it should read around 12.6 volts with the engine off.
Step 2: Start the engine and check the voltage at the battery; it should read between 13.5 to 14.5 volts, indicating proper alternator function.
Step 3: If either reading is off, replace the battery or the alternator as needed.
