Solution

1. Preparation

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

2. Address Fuel System Issues

Sub-steps:
1. Remove the fuel pump relay from the fuse box.
2. Connect a fuel pressure gauge to the fuel rail to check for proper pressure (should be around 40-50 psi).
3. If pressure is low, replace the fuel pump.
4. Inspect and replace the fuel filter if clogged.
5. Reconnect the fuel pump relay.

3. Inspect and Replace Spark Plugs

Sub-steps:
1. Remove the engine cover if applicable.
2. Disconnect the ignition coils by removing the electrical connectors.
3. Remove the ignition coils and spark plugs using a socket set.
4. Inspect spark plugs for wear; replace if necessary (gapping to manufacturer specifications).
5. Reinstall the ignition coils and reconnect electrical connectors.

4. Verify Throttle Position Sensor

Sub-steps:
1. Locate the throttle body and the TPS connected to it.
2. Disconnect the TPS electrical connector.
3. Use a multimeter to test the resistance values of the TPS; ensure they match manufacturer specifications.
4. Replace the TPS if readings are outside the specified range.
5. Reconnect the electrical connector.
