Solution

1. Preparation

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

2. Inspect Fuel Delivery System

Fuel Pump Check
- Remove the fuel pump relay from the fuse box.
- Use a multimeter to test the power supply to the fuel pump connector.
- If there is no power, check the wiring and connections.
Fuel Filter Replacement
- Locate the fuel filter (usually along the fuel line).
- Use a wrench to disconnect the fuel lines (be cautious of fuel spillage).
- Remove the old filter and install the new one, ensuring correct orientation.

3. Inspect Air Intake System

Air Filter Replacement
- Open the air filter housing and remove the old air filter.
- Clean the housing with a damp cloth.
- Install a new air filter, ensuring a tight seal.
Throttle Body Cleaning
- Remove the intake duct leading to the throttle body.
- Use throttle body cleaner and a soft cloth to clean the throttle plate and surrounding area.
- Reassemble the intake duct securely.

4. Test and Replace Spark Plugs/Coils

Spark Plug Inspection
- Remove spark plug wires or coils carefully.
- Use a spark plug socket to remove the spark plugs.
- Inspect for wear; replace if necessary with OEM-spec plugs.
Coil Inspection
- Check each ignition coil for cracks or damage.
- Replace any defective coils with new ones.
