Solution

1. Preparation

Gather tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.
Allow the engine to cool before proceeding.

2. Inspect and Replace Air Filter

Tools Required: Screwdriver or socket set
Remove the air filter housing cover.
Take out the old air filter and inspect for dirt or damage.
Install a new air filter, ensuring it fits snugly.
Reattach the housing cover securely.

3. Test and Replace Throttle Position Sensor (if faulty)

Tools Required: Multimeter, screwdriver
Disconnect the electrical connector from the TPS.
Use a multimeter to check the voltage output of the TPS while moving the throttle.
If the readings are out of specification, remove the TPS.
Install a new TPS and reconnect the electrical connector.

4. Inspect and Replace Spark Plugs

Tools Required: Socket set, torque wrench
Remove the ignition coil(s) to access the spark plugs.
Use a socket wrench to remove the spark plugs and inspect them for wear.
Replace with new spark plugs, ensuring the proper gap is set (consult specifications).
Reinstall the ignition coil(s) and torque them to the manufacturer-recommended values.

5. Check and Replace Fuel Pump (if necessary)

Tools Required: Fuel pressure gauge, socket set
Attach a fuel pressure gauge to the fuel rail.
Start the engine and check for proper fuel pressure.
If pressure is low, access the fuel pump by removing the rear seat or accessing the fuel tank.
Disconnect the fuel lines and electrical connector from the pump.
Replace the fuel pump with a new unit, reconnecting all lines securely.
