Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Address Fuel System Issues

Check Fuel Pump:
- Locate the fuel pump relay in the fuse box.
- Use a multimeter to test for voltage at the fuel pump connector.
- If no voltage is present, replace the relay or wiring as needed.
Replace Fuel Filter:
- Locate the fuel filter along the fuel line.
- Use a wrench to disconnect the fuel lines from the filter.
- Replace with a new fuel filter and reconnect the lines.

3. Clean the Throttle Body

Remove Throttle Body:
- Disconnect electrical connectors and vacuum hoses.
- Use a socket set to remove the throttle body mounting bolts.
- Carefully remove the throttle body from the intake manifold.
Clean Throttle Body:
- Use throttle body cleaner and a soft brush to clean the inside.
- Ensure the throttle plate moves freely without obstruction.
Reinstall Throttle Body:
- Reattach the throttle body and tighten bolts to manufacturer specifications (typically around 89 inch-lbs).
- Reconnect all electrical connectors and vacuum hoses.

4. Inspect and Replace Ignition Components

Check Spark Plugs:
- Remove spark plugs using a spark plug socket.
- Inspect for wear and replace if necessary (recommended gap: 0.054 inches).
Test Ignition Coils:
- Use a multimeter to check the resistance of each ignition coil.
- Replace any coils that do not meet specifications.
