Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Disconnect the battery to ensure safety during repairs.

2. Inspect and Clean Air Filter

Remove the air filter housing cover.
Take out the air filter and inspect it for dirt and damage.
Clean or replace the air filter as needed.
Reassemble the air filter housing.

3. Throttle Body Cleaning

Remove the throttle body from the intake manifold (remove any air intake ducts).
Use throttle body cleaner and a soft brush to clean the interior surfaces.
Ensure the throttle plate operates smoothly.
Reinstall the throttle body and reconnect any removed components.

4. Fuel Pump Testing

Connect a fuel pressure gauge to the fuel rail.
Turn the ignition to the "ON" position (without starting) and check pressure readings.
Compare the reading with manufacturer specifications; if low, replace the fuel pump.
Remove the gauge and reconnect the fuel line.

5. Ignition System Inspection

Remove spark plugs for inspection (look for wear patterns).
Replace worn or damaged spark plugs.
Inspect ignition coils for cracks or signs of failure; replace if necessary.
