Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the negative battery terminal to prevent electrical shorts.
Ensure the vehicle is parked on a flat surface and the engine is cool.

2. Fuel Filter Replacement

Tools Required: Socket set, fuel line disconnect tool, shop rags.
Sub-steps:
1. Relieve fuel system pressure by removing the fuel pump relay and starting the engine until it stalls.
2. Locate the fuel filter (usually near the fuel tank or along the fuel line).
3. Use the fuel line disconnect tool to detach the fuel lines from the filter carefully.
4. Remove the mounting bolts and take out the old filter.
5. Install the new fuel filter in the same orientation as the old one, securing it with mounting bolts.
6. Reconnect the fuel lines, ensuring they are securely attached.

3. Throttle Body Cleaning

Tools Required: Throttle body cleaner, soft brush, clean rags.
Sub-steps:
1. Remove the air intake duct connected to the throttle body.
2. Spray throttle body cleaner onto the throttle plate and inside the throttle body.
3. Use a soft brush to gently scrub any carbon buildup.
4. Wipe clean with a rag and ensure no cleaner residue is left.
5. Reattach the air intake duct securely.

4. Ignition System Inspection

Tools Required: Socket set, multimeter.
Sub-steps:
1. Remove the spark plug wires or ignition coil connectors.
2. Inspect spark plugs for wear, carbon fouling, or damage; replace if necessary.
3. Use a multimeter to check the resistance of the ignition coils; replace any coils that are out of specification.
4. Reconnect all ignition components once inspected.
