Solution

1. Preparation

Tools Required: OBD-II scanner, fuel pressure gauge, socket set, torque wrench, multimeter, vacuum gauge.
Disconnect the negative battery terminal to ensure safety during repairs.
Gather necessary replacement parts based on diagnostic findings.

2. Replace Fuel Filter (if clogged)

Sub-steps:
1. Locate the fuel filter (usually along the fuel line under the vehicle or near the fuel tank).
2. Relieve fuel system pressure by removing the fuel pump fuse and running the engine until it stalls.
3. Disconnect fuel lines from the filter using appropriate tools and note the orientation.
4. Remove the old filter and install the new one, ensuring the directional flow is correct.
5. Reconnect the fuel lines and secure them with clamps.

3. Inspect and Replace Air Filter (if dirty)

Sub-steps:
1. Open the hood and locate the air filter housing.
2. Unclip or unscrew the housing cover to access the air filter.
3. Remove the old air filter and inspect for dirt or debris.
4. Clean the housing using a vacuum or damp cloth.
5. Install the new air filter, ensuring it fits snugly, and reattach the housing cover.

4. Check and Replace Spark Plugs (if worn)

Sub-steps:
1. Locate the ignition coil packs and remove them to access the spark plugs.
2. Use a socket wrench to remove old spark plugs, inspecting them for wear or deposits.
3. Gap the new spark plugs to manufacturer specifications using a feeler gauge.
4. Install the new spark plugs and torque them to the specified value (refer to service manual).
5. Reattach the ignition coils and ensure connections are secure.
