Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Clean the Throttle Body

Use a throttle body cleaner and a soft cloth.
Remove the air intake duct connected to the throttle body.
Spray the cleaner into the throttle body and wipe it clean to remove carbon buildup.
Reattach the air intake duct securely.

3. Check and Replace Spark Plugs

Locate the ignition coils and remove them by unscrewing the bolts.
Gently pull out the spark plugs using a spark plug socket and ratchet.
Inspect each spark plug for wear; replace if necessary with OEM specifications (e.g., heat range, gap).
Reinstall the spark plugs and reconnect the ignition coils.

4. Fuel System Inspection

Use a fuel pressure gauge to check the pressure at the fuel rail; it should match manufacturer specifications.
If pressure is low, replace the fuel filter and check the fuel pump for functionality.
Ensure all fuel lines are intact without leaks.

5. Vacuum Leak Check

Inspect all vacuum hoses for cracks or disconnections; replace any damaged hoses.
Use a smoke machine or carburetor cleaner to identify any hidden vacuum leaks.
