Solution

1. Preparation

Gather all necessary tools and parts.
Ensure that the vehicle is parked on a flat surface with the engine off.
Disconnect the negative battery terminal.

2. Inspect and Clean the Throttle Body

Tools Required: Flathead screwdriver, throttle body cleaner, clean rags.
Remove the air intake duct to access the throttle body.
Spray throttle body cleaner into the throttle body and scrub with a clean rag until clean.
Reattach the air intake duct securely.

3. Fuel System Inspection

Tools Required: Fuel pressure gauge.
Locate the fuel rail and connect the fuel pressure gauge.
Turn the ignition to the "ON" position (without starting the engine) to check fuel pressure.
If pressure is low, inspect the fuel filter and pump for replacements.

4. Check Ignition Components

Tools Required: Socket set, multimeter.
Remove spark plugs and inspect for wear or carbon build-up.
Test ignition coils for continuity using a multimeter.
Replace any faulty spark plugs or ignition coils as necessary.

5. Address Battery and Electrical Connections

Tools Required: Wrench set, wire brush.
Inspect battery terminals for corrosion; clean with a wire brush if necessary.
Check the battery voltage; replace the battery if it reads below 12.4 volts.
