Socket set
Torque wrench
Multimeter

2. Address Fuel System Issues

2.1 Check Fuel Pressure

Connect the fuel pressure gauge to the fuel rail.
Turn the ignition on without starting the engine and note the pressure reading.
Compare the reading to the manufacturer specifications (usually around 40-50 psi).

2.2 Replace Fuel Filter (if necessary)

Locate the fuel filter (typically found along the fuel line).
Disconnect the fuel lines from the filter using a line removal tool.
Install the new filter in the correct orientation and reconnect the lines.

3. Inspect and Clean Components

3.1 Clean or Replace Air Filter

Remove the air filter housing cover.
Inspect the air filter for dirt and debris; replace if necessary.
Clean the air intake system with appropriate cleaners if excessive dirt is found.

3.2 Clean Fuel Injectors

Use a fuel injector cleaner or remove and clean the injectors using a specialized cleaning kit.
Reinstall the injectors, ensuring they are seated properly and secure.

4. Tire and Oil Maintenance

4.1 Check Tire Pressure

Use a tire pressure gauge to check all tires against the manufacturer’s specifications.
Inflate or deflate tires as necessary.

4.2 Change Engine Oil (if due)

Remove the oil drain plug and drain the old oil.
Replace the oil filter and refill with the appropriate type and amount of new oil.
