Solution

1. Preparation

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

2. Replace Air Filter

Locate the air filter housing.
Remove the screws or clips securing the housing.
Take out the old air filter and clean the housing.
Install a new air filter (ensure it meets OEM specifications).
Reassemble the housing and secure it.

3. Fuel System Inspection

Remove the fuel pressure gauge and connect it to the fuel rail.
Turn on the ignition (do not start the engine) to check fuel pressure readings against manufacturer specifications.
If pressure is low, check the fuel pump relay and fuses.
If necessary, replace the fuel pump.

4. Inspect and Replace Spark Plugs

Remove the ignition coil (if applicable) to access the spark plugs.
Use a spark plug socket to remove old spark plugs.
Inspect the old plugs for wear; replace with new ones if necessary (ensure correct gap).
Reinstall the ignition coils and reconnect any electrical connectors.

5. Clean Throttle Body

Remove the air intake duct to access the throttle body.
Use throttle body cleaner and a soft brush to clean the throttle plate and surrounding area.
Ensure the throttle plate moves freely without sticking.
Reassemble the intake duct.

6. Transmission Fluid Inspection

Locate the transmission dipstick (if applicable).
Check the fluid level and condition (should be bright red and clear).
If fluid is low or dirty, perform a fluid change or flush as necessary.
