Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the battery to ensure safety during electrical work.

2. Address Fault Codes

Using the OBD-II scanner, note any trouble codes and research their meanings.
Clear the codes and perform a test drive to see if they reappear.

3. Inspect and Replace Air Filter

Remove the engine cover if necessary.
Locate the air filter housing, unclip or unscrew the housing cover, and remove the old filter.
Install a new air filter, ensuring it fits securely, then close the housing.

4. Check and Replace Spark Plugs

Remove the ignition coils or wires from the spark plugs.
Use a socket set to remove old spark plugs.
Inspect the old plugs for wear; install new spark plugs (use manufacturer-recommended type and gap).
Reconnect the ignition coils or wires.

5. Inspect and Clean Throttle Body

Locate the throttle body and remove any air intake ducting.
Use throttle body cleaner and a soft cloth to clean the inside of the throttle body.
Reassemble the intake ducting after ensuring it is properly seated.

6. Test Fuel Pressure

Use a fuel pressure gauge to connect to the fuel rail.
Start the engine and check that the pressure matches manufacturer specifications.
If pressure is low, inspect and replace the fuel filter and/or fuel pump as needed.
