Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, fuel pressure gauge, torque wrench.
Ensure the vehicle is parked on a flat surface and the engine is cool. Disconnect the battery to prevent electrical shocks during repairs.

2. Air Filter Replacement

Remove the air intake duct using a socket set.
Take out the old air filter and inspect the filter housing for debris.
Install a new air filter, ensuring it is seated correctly.
Reattach the air intake duct and secure it.

3. Fuel System Check

Tools Required: Fuel pressure gauge.
Locate the fuel rail and connect the fuel pressure gauge to the test port.
Start the engine and check the fuel pressure against manufacturer specifications. Replace the fuel pump or filter if pressure is low.
Disconnect the gauge and ensure all connections are secure.

4. Throttle Body Cleaning

Remove the throttle body from the intake manifold using a socket set.
Clean the throttle body using a throttle body cleaner and a soft brush to remove carbon buildup.
Reinstall the throttle body, ensuring all gaskets are replaced and connections are tight.

5. Ignition System Replacement

Remove spark plug wires or ignition coil connectors.
Replace old spark plugs with new ones, ensuring correct gap settings.
If ignition coils show signs of failure, replace them as well.
Reconnect all wiring and components.
