Solution

1. Preparation

Gather tools and parts needed.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to ensure safety during repairs.

2. Air Filter Replacement

Remove the air intake duct using a socket set.
Take out the old air filter and inspect the airbox for debris.
Install a new, clean air filter, ensuring it fits snugly.
Reassemble the air intake duct and tighten all fasteners.

3. Fuel System Inspection

Connect the fuel pressure gauge to the fuel rail.
Start the engine and check that fuel pressure is within specifications (consult manufacturer’s manual).
If pressure is low, inspect the fuel pump and fuel filter for issues.
Replace the fuel filter if necessary and consider replacing the fuel pump if it’s not functioning properly.

4. Exhaust Inspection

Inspect the exhaust system visually for any signs of damage or blockage.
If a clogged catalytic converter is suspected, perform a backpressure test.
If the catalytic converter is found to be faulty, replace it with an OEM equivalent.

5. Transmission Fluid Check

Locate the transmission dipstick and remove it to check fluid level and condition.
If the fluid is low or burnt, drain the old fluid and replace it with the manufacturer's recommended transmission fluid.
If issues persist, consider having the transmission serviced by a professional.
