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 prevent electrical shorts.

2. Inspect and Replace Air Filter

Remove the air filter housing cover.
Take out the old air filter and visually inspect it for dirt and damage.
Install a new air filter that meets manufacturer specifications.
Reassemble the air filter housing.

3. Fuel System Check

Connect a fuel pressure gauge to the fuel rail.
Turn the ignition to the "ON" position without starting the engine to check for proper fuel pressure.
If pressure is low, inspect the fuel pump and replace it if necessary.
Replace the fuel filter if it shows signs of clogging.

4. Clean or Replace Throttle Body

Remove the intake duct connected to the throttle body.
Use throttle body cleaner and a soft cloth to clean the throttle plate and surrounding area.
If the throttle body is damaged, replace it with a new one.

5. Inspect Ignition System

Remove the spark plugs and inspect them for wear or fouling.
Replace any worn or damaged spark plugs.
Check ignition coils for proper function and replace if necessary.

6. Check for Vacuum Leaks

Inspect all vacuum hoses and connections for cracks or disconnections.
Use a smoke machine to detect leaks in the intake system if necessary.
Replace any damaged hoses or seals.
