Solution

1. Preparation

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

2. Replace Air Filter

Tools Required: Socket set, screwdriver
Remove the air filter housing cover.
Take out the old air filter and insert a new one, ensuring it fits snugly.
Reattach the housing cover securely.

3. Fuel System Inspection

Tools Required: Fuel pressure gauge
Locate the fuel rail and attach the fuel pressure gauge.
Start the engine and check the pressure reading against manufacturer specifications.
If pressure is low, inspect the fuel pump and replace if necessary.

4. Clean Throttle Body

Tools Required: Throttle body cleaner, soft cloth
Remove the air intake duct to access the throttle body.
Spray throttle body cleaner onto a clean cloth and wipe the throttle plate and inside of the throttle body.
Reassemble the air intake duct securely.

5. Inspect and Replace Spark Plugs

Tools Required: Socket set, torque wrench
Remove the ignition coils or spark plug wires to access the spark plugs.
Use a spark plug socket to remove old spark plugs.
Install new spark plugs with the correct gap and torque them to manufacturer specifications.

6. Exhaust System Check

Tools Required: Jack and jack stands
Lift the vehicle and visually inspect the exhaust for blockages, dents, or rust.
If a blockage is found, remove the affected section of the exhaust and replace it with a new component.
