Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Clean the Throttle Body

Tools Required: Throttle body cleaner, soft brush, and rags.
Sub-steps:
1. Remove the air intake duct to access the throttle body.
2. Spray throttle body cleaner into the throttle body and scrub gently with a soft brush.
3. Wipe clean with a rag and allow it to dry before reassembling.

3. Replace Fuel Filter (if applicable)

Tools Required: Wrenches or socket set, safety goggles.
Sub-steps:
1. Locate the fuel filter, usually in the fuel line near the fuel tank.
2. Relieve fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls.
3. Disconnect the fuel lines from the filter, taking care to catch any spilled fuel.
4. Install the new fuel filter in the same orientation as the old one and reconnect the fuel lines.

4. Inspect and Replace Spark Plugs (if needed)

Tools Required: Socket set, torque wrench, spark plug gap tool.
Sub-steps:
1. Remove ignition coils by unscrewing them from their mounting points.
2. Use a socket wrench to remove the spark plugs.
3. Check the gap on the new spark plugs and adjust as necessary.
4. Install the new spark plugs and torque them to the manufacturer’s specifications (typically around 13 lb-ft).
5. Reinstall the ignition coils securely.

5. Check for Vacuum Leaks

Tools Required: Smoke machine or carburetor cleaner.
Sub-steps:
1. Inspect all vacuum hoses for cracks or disconnections.
2. Use a smoke machine to detect leaks by introducing smoke into the intake system.
3. Repair or replace any damaged hoses.
