Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and turn off the engine.
Disconnect the negative battery terminal to avoid electrical issues during repair.

2. Change the Air Filter

Remove the air filter housing cover by unscrewing any fasteners.
Take out the old air filter and clean the housing if necessary.
Install the new air filter, ensuring it fits snugly.
Reattach the air filter housing cover securely.

3. Replace the Fuel Filter

Locate the fuel filter and relieve the fuel pressure by removing the fuel pump fuse and running the engine until it stalls.
Disconnect the fuel lines from the filter using a line disconnect tool, ensuring to capture any spilled fuel.
Remove the old fuel filter and install the new one in the correct orientation.
Reconnect the fuel lines and replace the fuel pump fuse.

4. Check and Change Transmission Fluid (if necessary)

Raise the vehicle and secure it on jack stands.
Remove the transmission pan bolts to drain the old fluid into a suitable container.
Replace the transmission filter if applicable.
Reinstall the pan with a new gasket and torque bolts to manufacturer specifications.
Refill the transmission with new fluid through the dipstick tube, using the correct type of fluid.

5. Test Fuel Pressure

Connect the fuel pressure gauge to the fuel rail test port.
Start the engine and observe the fuel pressure reading.
Compare the reading to manufacturer specifications; if it is low, further investigation into the fuel pump may be necessary.
