Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety.
Allow the engine to cool before beginning work.

2. Inspect and Replace the Air Filter

Sub-steps:
1. Locate the air filter housing.
2. Open the housing and remove the old air filter.
3. Inspect the air filter for dirt and blockages.
4. Replace with a new, clean air filter.
5. Reassemble the air filter housing.

3. Test and Replace the Fuel Filter

Sub-steps:
1. Locate the fuel filter (or fuel pump assembly if integrated).
2. Relieve fuel system pressure as per manufacturer instructions.
3. Disconnect the fuel lines carefully.
4. Remove the old fuel filter and replace it with a new one.
5. Reconnect fuel lines and check for leaks.

4. Inspect and Test the Throttle Position Sensor (TPS)

Sub-steps:
1. Locate the TPS on the throttle body.
2. Disconnect the TPS connector.
3. Use a multimeter to check the TPS resistance according to specifications.
4. Replace the TPS if it is out of specification.
5. Reconnect the TPS connector.

5. Replace Spark Plugs and Inspect Ignition Coils

Sub-steps:
1. Remove the ignition coils from the spark plugs.
2. Remove and inspect spark plugs for wear; replace if necessary.
3. Check ignition coils for proper operation; replace any faulty coils.
4. Reassemble ignition components ensuring proper torque specifications.
