Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Air Filter

Locate the air filter housing.
Open the housing by removing the clips or screws.
Remove the old air filter and inspect it for dirt and debris.
Install a new air filter, ensuring it is seated properly.
Reassemble the air filter housing.

3. Check Fuel System

Locate the fuel pressure test port on the fuel rail.
Connect a fuel pressure gauge and turn the ignition to the "ON" position without starting the engine.
Check the fuel pressure against manufacturer specifications.
If pressure is low, replace the fuel pump and filter if necessary.

4. Throttle Body Cleaning

Disconnect the throttle body electrical connector.
Remove the intake duct leading to the throttle body.
Use throttle body cleaner and a soft cloth to clean the throttle plate and housing.
Reassemble all components and reconnect the electrical connector.

5. Exhaust System Inspection

Visually inspect the exhaust system from the manifold to the tailpipe for any signs of damage or blockage.
If a restriction is found, replace the affected exhaust component (e.g., catalytic converter).
Ensure all exhaust connections are tight.
