Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to avoid electrical issues during inspection.

2. Check Oil Type and Level

Remove the dipstick and clean it with a cloth.
Reinsert the dipstick and remove it again to check the oil level.
If the oil is below the minimum mark, top off with the correct oil type as specified in the owner's manual.

3. Inspect Oil Filter

Locate the oil filter and check for proper installation; ensure it is securely tightened.
If the filter appears damaged or improperly installed, replace it with a new one.
Ensure the rubber O-ring is not stuck to the engine block.

4. Scan for Error Codes

Use the OBD-II scanner to check for any error codes.
Address any codes that indicate sensor or performance issues.

5. Inspect Intake and Exhaust Systems

Visually inspect the air intake for any blockages, such as debris or a damaged air filter.
Check the exhaust system for any signs of obstruction or leaks.

6. Test Throttle Response

Reconnect the battery.
Start the vehicle and check the responsiveness of the throttle.
If sluggishness persists, consider resetting the throttle position sensor if applicable.
