Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the negative terminal of the battery to ensure safety during repairs.

2. Inspect and Replace Spark Plugs

Sub-steps:
1. Remove the engine cover if applicable.
2. Unscrew and remove the spark plug wires or ignition coils.
3. Use a spark plug socket to remove the old spark plugs.
4. Inspect the spark plugs for wear or fouling; replace if necessary.
5. Gap new spark plugs to factory specifications and install them.
6. Reattach ignition coils or spark plug wires securely.

3. Check Fuel System

Sub-steps:
1. Locate the fuel filter and inspect it for clogs or damage.
2. If necessary, replace the fuel filter with a new one.
3. Check the fuel pump operation by listening for the pump when the ignition is turned to the "ON" position.
4. If the fuel pump is malfunctioning, replace it according to manufacturer specifications.

4. Inspect Throttle Position Sensor

Sub-steps:
1. Locate the throttle position sensor on the throttle body.
2. Disconnect the electrical connector and inspect for corrosion or damage.
3. Use a multimeter to test the TPS for proper voltage readings at various throttle positions.
4. Replace the TPS if it does not meet specifications.
