Solution

1. Preparation

Gather all necessary tools: OBD-II scanner, fuel pressure gauge, socket set, torque wrench, and multimeter.
Ensure the vehicle is on a level surface and the engine is cool.
Disconnect the battery before working on any electrical components.

2. Address Fuel Injectors

Remove the intake manifold (if necessary to access injectors).
- Use a socket set to remove bolts securing the manifold.
Inspect fuel injectors.
- Remove the electrical connectors and fuel lines from the injectors.
- Check for fuel leaks and any signs of carbon buildup.
Clean or replace injectors.
- Use a fuel injector cleaning kit or replace with new injectors if necessary.
Reassemble the intake manifold.
- Torque the bolts to the manufacturer's specifications.

3. Replace Air Filter

Locate the air filter housing.
- Usually found near the front of the engine compartment.
Remove the air filter.
- Open the housing and take out the old filter.
Install a new air filter.
- Ensure a snug fit to prevent unfiltered air from entering the engine.

4. Adjust Tire Pressure

Check tire pressure using a tire pressure gauge.
Inflate or deflate tires to the recommended PSI as per the owner’s manual.
Inspect tire condition for excessive wear or misalignment.

5. Fuel System Evaluation

Check fuel pressure using a fuel pressure gauge.
- Connect the gauge according to the manufacturer's instructions.
- Compare the reading to the specifications in the service manual.
Replace fuel filter if pressure is low or if there are signs of clogging.
