Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, torque wrench, fuel pressure gauge, vacuum gauge.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Address Error Codes

If DTCs are present, research each code and address the related issues.
Clear the codes using the OBD-II scanner and test drive to see if they return.

3. Replace Air Filter

Remove the air filter housing cover using a socket set.
Take out the old air filter and inspect the housing for dirt.
Install a new air filter and reassemble the housing securely.

4. Inspect and Replace Fuel Filter (if necessary)

Locate the fuel filter along the fuel line.
Relieve fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls.
Disconnect fuel lines from the filter using appropriate wrenches, ensuring no fuel spills.
Replace the old filter with a new one, reattach the fuel lines, and restore the fuel pump fuse.

5. Test Fuel Pressure

Connect the fuel pressure gauge to the fuel rail service port.
Start the engine and check that the fuel pressure meets manufacturer specifications (typically around 40-50 PSI).
If pressure is low, inspect the fuel pump and replace it if necessary.

6. Check and Replace Spark Plugs

Remove the ignition coils or spark plug wires.
Use a socket set to unscrew the spark plugs and inspect them for wear or carbon buildup.
Replace with new spark plugs, ensuring to torque them to specifications (usually around 13-15 ft-lbs).
