Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety during repairs.
Ensure the vehicle is on a level surface and secure with jack stands if needed.

2. Inspect and Clean Throttle Body

Remove the air intake duct by loosening the clamps and disconnecting any connectors.
Using a throttle body cleaner and a soft cloth, clean the throttle body interior, removing carbon buildup.
Inspect the throttle plate for free movement; if stuck, apply some lubricant and operate it manually.
Reinstall the air intake duct, ensuring all clamps and connectors are secured.

3. Test and Replace Fuel Pump and Filter

Locate the fuel pump access panel under the rear seat or trunk area.
Disconnect the negative battery terminal.
Relieve fuel pressure by removing the fuel pump relay and starting the engine until it stalls.
Remove the fuel pump assembly and replace the fuel filter if it is integrated.
Reinstall the assembly and reconnect the battery.

4. Inspect and Replace Ignition Components

Remove spark plug wires or coils to access the spark plugs.
Inspect spark plugs for wear; replace if they are worn or fouled.
Test ignition coils with a multimeter for resistance; replace any that do not meet specifications.
Reassemble all components ensuring proper alignment.
