Solution

1. Preparation

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

2. Clean the Throttle Body

Tools Required: Throttle body cleaner, soft cloth, screwdriver
Remove the air intake duct to access the throttle body.
Spray throttle body cleaner onto a soft cloth and wipe the inside of the throttle body, focusing on the throttle plate and surrounding areas.
Reassemble the air intake duct and reconnect the battery.

3. Replace the Fuel Filter

Tools Required: Socket set, fuel line disconnect tool
Locate the fuel filter (usually along the fuel line).
Relieve fuel system pressure by removing the fuel pump relay and starting the engine until it stalls.
Disconnect the fuel lines using a fuel line disconnect tool.
Remove the old fuel filter and install the new one, ensuring correct orientation of flow direction.
Reconnect the fuel lines and reinstall the fuel pump relay.

4. Inspect and Clean the MAF Sensor

Tools Required: MAF cleaner, small screwdriver
Locate the MAF sensor, typically positioned between the air filter and the throttle body.
Disconnect the electrical connector and remove the sensor from the intake.
Spray MAF cleaner on the sensor’s sensing elements without touching them. Allow it to dry completely before reinstalling.
Reattach the MAF sensor and connector.

5. Check for Vacuum Leaks

Tools Required: Smoke machine (optional), hose, clamps
Visually inspect all vacuum hoses for cracks or disconnections.
If available, use a smoke machine to introduce smoke into the intake system and check for smoke leaks.
Repair or replace any damaged hoses.
