Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.

2. Retrieve Error Codes

Tools Required: OBD-II scanner
Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn the ignition to the "ON" position without starting the engine.
Follow the scanner instructions to read and record any error codes.

Ensure the gas cap is securely tightened.
If damaged, replace the gas cap with a manufacturer-approved part.

4. Check Engine Oil

Tools Required: Oil dipstick, funnel, engine oil
Remove the oil dipstick, wipe it clean, and reinsert it.
Check the oil level; add oil if necessary, using the recommended type.
Inspect for any signs of contamination (milky appearance) indicating a possible head gasket issue.

Locate the air filter housing and remove the cover.
Take out the air filter and inspect it for dirt and debris.
Replace the air filter if it is clogged or excessively dirty.

6. Examine Spark Plugs
