Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a flat surface and the engine is cool.
• Disconnect the battery to ensure safety during repairs.

2. Inspect and Replace Air Filter

• Locate the air filter housing.
• Open the housing and remove the old air filter.
• Check the filter for dirt; if dirty, replace it with a new one.
• Reassemble the air filter housing securely.

3. Check and Replace Fuel Filter (if applicable)

• Locate the fuel filter; refer to the service manual for the specific location.
• Relieve fuel system pressure by disconnecting the fuel pump fuse and running the engine until it stalls.
• Disconnect the fuel lines from the filter using the appropriate tools.
• Replace the old fuel filter with a new one, ensuring correct orientation.
• Reconnect the fuel lines and fuse, and check for leaks.

4. Clean Throttle Body

• Remove the air intake duct to access the throttle body.
• Use throttle body cleaner and a soft cloth to clean the throttle plate and surrounding area.
• Ensure that the throttle plate operates smoothly without binding.
• Reattach the air intake duct securely.

5. Inspect and Replace Ignition Components

• Remove the ignition coil(s) from the engine.
• Inspect spark plugs for wear; replace if necessary with OEM or equivalent parts.
• Test ignition coils with a multimeter, replacing any that are out of specifications.
• Reinstall coils and reconnect wiring.

6. Check for Vacuum Leaks

• Inspect all vacuum hoses connected to the intake manifold for cracks or disconnections.
• Use a smoke machine or carburetor cleaner to identify leaks while the engine is running.
• Replace any damaged hoses and ensure all connections are tight.
