Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety during electrical inspections.
Allow the engine to cool if it has been running.

2. Air Filter Replacement

Locate the air filter housing.
Remove the screws or clips securing the housing.
Take out the old air filter and inspect the housing for any debris.
Install a new air filter, ensuring it fits snugly in the housing.
Re-secure the housing with screws or clips.

3. Fuel Pressure Test

Connect the fuel pressure gauge to the fuel rail test port.
Turn the ignition to the "ON" position without starting the engine to check fuel pressure.
Compare the reading to the manufacturer's specifications (usually found in service manual).
If the pressure is low, replace the fuel pump or check for blocked fuel lines.

4. Throttle Body Cleaning

Remove the intake duct connected to the throttle body.
Using throttle body cleaner and a clean cloth, carefully clean the throttle plate and surrounding area.
Ensure no cleaner residue is left behind.
Reattach the intake duct securely.

5. Inspect Spark Plugs

Remove the ignition coil(s) or spark plug wires.
Use a socket wrench to remove the spark plugs.
Inspect each spark plug for wear, carbon buildup, or damage.
Replace worn or damaged spark plugs with new ones, tightening them to the manufacturer’s torque specifications.
