Solution

1. Preparation

Gather tools and parts as listed below.
Disconnect the negative terminal of the battery to prevent electrical shorts.
Allow the engine to cool before beginning work.

2. Fuel System Inspection

Check Fuel Pump Operation
- Locate the fuel pump relay and test it with a multimeter.
- If faulty, replace the fuel pump relay.
Inspect Fuel Filter
- Locate the fuel filter, typically along the fuel line.
- Replace the fuel filter if it shows signs of clogging or is due for replacement.

3. Air Intake System Check

Inspect Air Filter
- Remove the air filter housing cover.
- Replace the air filter if dirty or clogged.
Clean Throttle Body
- Gain access to the throttle body by removing the intake duct.
- Use throttle body cleaner and a soft cloth to clean the inside of the throttle body.

4. Ignition System Repair

Check and Replace Spark Plugs
- Remove spark plugs using a socket and ratchet.
- Inspect for wear; replace with OEM specifications if necessary.
Test and Replace Ignition Coils
- Disconnect the electrical connector from the ignition coils.
- Use a multimeter to test the resistance; replace any faulty coils.

5. Reassembly and Connection

Reinstall all components in reverse order of removal.
Reconnect the negative battery terminal.
Ensure all connections are secure and tight.
