Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface, and the engine is cool.
Disconnect the negative battery terminal to prevent electrical issues.

2. Inspect and Replace Air Filter

Remove the air filter housing cover using a socket set.
Take out the old air filter and visually inspect it for dirt or damage.
Install a new, clean air filter, ensuring it fits securely in the housing.
Reattach the air filter housing cover and tighten the screws to the manufacturer's specifications.

3. Check and Replace Fuel Pump (if necessary)

Locate the fuel pump access panel (usually under the rear seat or in the trunk).
Disconnect the fuel lines and electrical connectors from the pump.
Remove the retaining ring and lift the fuel pump out of the tank.
Install the new fuel pump and replace the retaining ring, ensuring a secure fit.
Reconnect the fuel lines and electrical connectors.

4. Inspect Exhaust System

Visually examine the exhaust system for any signs of damage or blockages.
If a clogged catalytic converter is suspected, remove it from the exhaust system for inspection.
If clogged, replace the catalytic converter with a new unit.

5. Test and Replace Ignition Components (if necessary)

Remove spark plugs using a spark plug socket and inspect them for wear or fouling.
Replace any faulty spark plugs with OEM or equivalent parts.
Test ignition coils for proper function and replace any that are defective.
