Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety during repairs.

2. Inspect and Replace Air Filter

Remove the air filter housing cover using a socket set.
Take out the air filter and check for dirt or damage.
Replace with a new air filter if necessary.
Reassemble the air filter housing.

3. Fuel System Inspection

Attach a fuel pressure gauge to the fuel rail.
Start the engine and observe the fuel pressure reading; it should match the manufacturer’s specifications.
If pressure is low, check the fuel pump and fuel filter for blockages.
Replace the fuel filter if it shows signs of clogging.

4. Throttle Body Cleaning

Remove the throttle body by disconnecting the intake hoses and electrical connectors.
Clean the throttle body using throttle body cleaner and a soft cloth to remove carbon buildup.
Reinstall the throttle body and reconnect all hoses and connectors.

5. Exhaust System Check

Inspect the exhaust system for any physical damage or blockages.
If the catalytic converter appears clogged, replace it with a new unit.
Ensure all exhaust connections are tight to prevent leaks.
