Solution

1. Preparation

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

2. Fuel System Inspection

Step 1: Check fuel pressure using a fuel pressure gauge.
- Tools Required: Fuel pressure gauge
- If pressure is low, replace the fuel filter and inspect the fuel pump.
Step 2: Replace the fuel filter if clogged.
- Tools Required: Socket set, line wrenches
- Safety Warning: Relieve fuel system pressure before disconnecting lines.

3. Throttle Body Cleaning

Step 1: Remove the intake duct to access the throttle body.
- Tools Required: Screwdriver, socket set
Step 2: Use throttle body cleaner to remove carbon buildup.
Step 3: Reinstall the intake duct securely.

4. Ignition System Check

Step 1: Remove and inspect spark plugs for wear or damage.
- Tools Required: Spark plug socket, torque wrench
Step 2: Replace any worn or damaged spark plugs with OEM parts.
- Torque to manufacturer specifications (typically around 13 ft-lbs).
