Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Air Filter

Remove the air filter housing cover using a socket set.
Take out the old air filter and inspect for dirt or blockage.
Install a new air filter (ensure it is the correct part for the 2024 Mustang S650).
Reattach the air filter housing cover securely.

3. Check and Replace Fuel Filter

Locate the fuel filter along the fuel line.
Relieve fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls.
Disconnect the fuel lines from the filter using a line removal tool.
Replace the old fuel filter with a new one, ensuring proper orientation.
Reconnect the fuel lines and reinsert the fuel pump fuse.

4. Inspect and Replace Spark Plugs

Remove the ignition coil covers using a socket set.
Disconnect the ignition coils and remove them from the spark plugs.
Use a spark plug socket to remove old spark plugs and inspect for wear.
Install new spark plugs with the recommended gap specification for the S650.
Reattach the ignition coils and covers.

5. Test Throttle Position Sensor (TPS)

Disconnect the electrical connector from the TPS.
Use a multimeter to measure the voltage output of the TPS while manually moving the throttle.
If the output is outside manufacturer specifications, replace the TPS.
Reconnect the electrical connector to the new TPS.
