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 Replace Air Filter

Remove the air filter housing cover using a socket set.
Take out the existing air filter and inspect it for dirt and blockages.
Replace with a new air filter if necessary.
Reassemble the air filter housing and securely tighten the cover.

3. Fuel Pressure Test

Connect a fuel pressure gauge to the fuel rail.
Start the engine and monitor the fuel pressure; it should meet manufacturer specifications (usually around 40-50 psi).
If pressure is low, inspect the fuel pump and filter for any issues and replace if needed.

4. Clean Throttle Body

Remove the throttle body using a socket set, ensuring to disconnect the electrical connectors and vacuum lines.
Use throttle body cleaner and a soft cloth to clean the inside of the throttle body.
Reinstall the throttle body and reconnect all electrical connectors and hoses.

5. Inspect and Replace Spark Plugs/Ignition Coils

Remove the ignition coil covers as needed, using a socket set.
Inspect spark plugs for wear; replace them if they appear worn or fouled.
Test ignition coils using a multimeter; replace any defective coils.
Reinstall all components and ensure they are securely fastened.
