Solution

1. Preparation

Tools Required: OBD-II scanner, fuel pressure gauge, multimeter, socket set, torque wrench.
Ensure the vehicle is parked on a level surface and the engine is turned off before starting.

2. Address Fuel System Issues

Sub-steps:
1. Locate the fuel pressure test port on the fuel rail.
2. Connect the fuel pressure gauge and turn the ignition to the "ON" position (do not start the engine).
3. Check the fuel pressure reading; it should be within the manufacturer’s specifications (typically around 40-50 psi). If low, check the fuel pump and fuel filter.
4. If the fuel filter is clogged, replace it according to the service manual.

3. Replace Air Filter

Sub-steps:
1. Open the hood and locate the air filter housing.
2. Remove the clips or screws to access the air filter.
3. Inspect the filter; if dirty, replace it with a new one according to manufacturer specifications.
4. Reassemble the air filter housing securely.

4. Test and Replace Spark Plugs and Ignition Coils

Sub-steps:
1. Remove the ignition coils by unscrewing them from the cylinder head.
2. Take out the spark plugs using a spark plug socket.
3. Inspect the spark plugs for wear; replace if necessary with OEM specifications.
4. Reinstall the ignition coils and ensure they are torqued to the manufacturer's specifications.

5. Check and Replace Throttle Position Sensor

Sub-steps:
1. Disconnect the battery to prevent electrical shorts.
2. Locate the TPS on the throttle body and disconnect the electrical connector.
3. Remove the screws holding the TPS and replace it with a new unit if it is malfunctioning.
4. Reconnect the electrical connector and reconnect the battery.
