Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is on a level surface and the engine is cool.
• Disconnect the negative battery terminal to ensure safety.

2. Clean the Throttle Body

• Tools Required: Throttle body cleaner, soft cloth, screwdriver.
• Remove the air intake duct connected to the throttle body.
• Spray throttle body cleaner onto the throttle plate and inside the throttle body.
• Wipe clean with a soft cloth until free of deposits.

3. Replace the Air Filter

• Tools Required: Screwdriver or pliers (if necessary).

4. Test and Replace Fuel Pump (if needed)

• Tools Required: Fuel pressure gauge, socket set.
