Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and the engine is cool.
Disconnect the negative battery terminal for safety.

2. Inspect and Replace Air Filter

Remove the air filter housing cover using a socket set.
Take out the old air filter and inspect for dirt or damage.
Install a new air filter ensuring it fits properly.
Reattach the air filter housing cover and tighten screws.

3. Fuel System Inspection

Reconnect the battery terminal.
Attach a fuel pressure gauge to the fuel rail.
Start the engine and monitor the fuel pressure readings; it should meet manufacturer specifications.
If pressure is low, inspect the fuel pump and replace if necessary.

4. Throttle Body Cleaning

Disconnect the throttle body electrical connector and remove the throttle body using a socket set.
Clean the throttle plate and intake manifold with a throttle body cleaner.
Reinstall the throttle body and reconnect the electrical connector.

5. Ignition System Check

Remove spark plugs using a socket wrench and inspect for wear and deposits.
Replace any faulty spark plugs with OEM specifications.
Check ignition coils for proper resistance using a multimeter and replace as necessary.
