Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the negative battery terminal to ensure 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 it for dirt and blockages.
Replace with a new air filter (OEM recommended) and reassemble the housing.

3. Fuel System Inspection

Connect the fuel pressure gauge to the fuel rail.
Turn the ignition on without starting the engine and check the pressure reading against manufacturer specifications.
If pressure is low, inspect the fuel pump, fuel filter, and fuel lines for blockages or failures.
Replace any faulty components.

4. Ignition System Inspection

Remove spark plug wires and spark plugs using a spark plug socket.
Inspect for wear, carbon buildup, or damage.
Replace spark plugs with OEM equivalents if necessary.
Reinstall spark plugs and wires securely.

5. Throttle Body Cleaning

Remove the throttle body from the intake manifold using a socket set.
Clean the throttle body with throttle body cleaner and a soft cloth.
Reinstall the throttle body and ensure all connections are secure.

6. Exhaust System Check

Visually inspect the exhaust system for dents, rust, or damage.
If a clogged catalytic converter is suspected, perform a back pressure test.
Replace the catalytic converter if it is found to be defective.
