Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the battery to prevent electrical issues during repairs.

2. Address Fuel System Issues

Fuel Pump Replacement:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Remove the fuel pump access panel (if applicable) or the fuel tank.
3. Disconnect the electrical connector and fuel lines from the pump.
4. Remove the fuel pump from the tank and replace with a new pump.
5. Reconnect the fuel lines and electrical connector.
Fuel Filter Replacement:
1. Locate the fuel filter along the fuel line (check service manual for exact location).
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 a line wrench.
4. Replace the old filter with a new one and reconnect the lines.

3. Repair Air Intake System

Cleaning MAF Sensor:
1. Remove the MAF sensor from the air intake duct.
2. Use MAF cleaner spray to clean the sensor gently.
3. Allow it to dry completely before reinstalling.
Inspecting the Air Filter:
1. Remove the air filter housing cover.
2. Check the air filter for dirt and debris.
3. Replace with a new filter if it is dirty or damaged.

4. Check Ignition System

Spark Plug Replacement:
1. Remove the ignition coil cover (if applicable).
2. Disconnect the ignition coils and remove them from the spark plugs.
3. Remove the old spark plugs using a spark plug socket.
4. Install new spark plugs, ensuring proper gap specifications are met.
5. Reattach the ignition coils.

5. Inspect Throttle Position Sensor

Testing and Replacement:
1. Disconnect the TPS connector.
2. Use a multimeter to check voltage readings at the TPS terminals.
3. If readings are out of specification, replace the TPS with a new unit.
