Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, torque wrench, multimeter, fuel pressure gauge.
Ensure the vehicle is parked on a flat surface, and engage the parking brake.
Disconnect the battery before working on electrical systems.

2. Address Engine Codes

Use the OBD-II scanner to read and record any trouble codes.
Clear the codes and perform a test drive to see if they return, indicating the underlying issue.

3. Clean the Throttle Body

Remove the air intake duct leading to the throttle body.
Use throttle body cleaner and a soft cloth to clean the throttle plate and surrounding area.
Reattach the intake duct and ensure all clamps are tight.

4. Inspect and Replace Fuel Filter

Locate the fuel filter; it's usually near the fuel tank or along the fuel line.
Relieve fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls.
Disconnect the fuel lines from the filter and remove it using the appropriate tools.
Install the new fuel filter, ensuring proper orientation, and reconnect the fuel lines.

5. Check and Replace Spark Plugs

Remove the ignition coil covers, if applicable.
Use a socket wrench to remove the spark plugs and inspect them for wear or fouling.
Replace with OEM or equivalent spark plugs, ensuring the correct gap.
Reinstall ignition coils and covers.

6. Test Drive and Monitor

Reconnect the battery.
Take the vehicle for a test drive to assess acceleration improvements.
Monitor for any unusual sounds or warning lights.
