Solution

1. Preparation

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

2. Air Filter Replacement

Remove the air filter housing cover using a socket set.
Take out the old air filter and inspect the housing for debris.
Install a new air filter (OEM recommended) ensuring a secure fit.
Reattach the air filter housing cover and tighten securely.

3. Fuel Pressure Check

Locate the fuel rail on the engine.
Connect the fuel pressure gauge to the Schrader valve on the fuel rail.
Start the engine and observe the fuel pressure reading; it should meet manufacturer specifications (usually around 58-65 psi).
If low, check the fuel pump and filter for issues.

4. Throttle Body Cleaning

Remove the intake duct connected to the throttle body.
Use throttle body cleaner and a soft brush to clean the throttle plate and surrounding areas.
Reinstall the intake duct securely.

5. Transmission Fluid Check

Remove the transmission dipstick (if equipped).
Check the fluid level; it should be within the marked range.
If low, add the appropriate transmission fluid (refer to the owner's manual for specification).
Inspect fluid for discoloration or burning smell, indicating a need for a fluid change.

6. Exhaust System Inspection

Visually inspect the exhaust system for any damage or blockages, particularly the catalytic converter.
If any damage is found, replace the affected components.
