Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Replace Fuel Filter

Tools Required: Socket set, fuel line disconnect tool, rags.
Sub-steps:
1. Locate the fuel filter, usually found along the fuel line.
2. Relieve fuel system pressure by removing the fuel pump fuse and running the engine until it stalls.
3. Disconnect the fuel lines from the filter using the fuel line disconnect tool.
4. Remove the old fuel filter and install the new one, ensuring correct orientation.
5. Reconnect the fuel lines and replace the fuel pump fuse.

3. Inspect Fuel Pump

Tools Required: Fuel pressure gauge, socket set.
Sub-steps:
1. Connect the fuel pressure gauge to the fuel rail test port.
2. Turn the ignition on (do not start the engine) to check for proper fuel pressure.
3. If pressure is low, replace the fuel pump.
4. Refer to the service manual for specific pressure values and pump replacement procedures.

4. Check Throttle Position Sensor (TPS)

Tools Required: Multimeter, socket set.
Sub-steps:
1. Locate the TPS on the throttle body.
2. Disconnect the TPS electrical connector.
3. Use a multimeter to measure voltage across the terminals while slowly moving the throttle.
4. If the voltage does not change smoothly, replace the TPS with a new one.
