Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative terminal of the battery to prevent electrical shock.
Ensure the vehicle is on a level surface and use wheel chocks for safety.

2. Inspect and Replace Spark Plugs

Tools Required: Socket set, torque wrench, gap gauge.
Remove the ignition coil cover.
Disconnect the ignition coils from the spark plugs.
Remove the old spark plugs using a socket wrench.
Inspect each spark plug for wear; replace if necessary.
Set the gap on new spark plugs to manufacturer specifications.
Install new spark plugs and reconnect ignition coils.

3. Clean or Replace Air Filter

Tools Required: Screwdriver (if needed).
Remove the air filter housing cover.
Take out the old air filter and inspect it for dirt and damage.
If dirty, replace it with a new air filter.
Reassemble the air filter housing.

4. Clean Throttle Body

Tools Required: Throttle body cleaner, soft cloth, screwdriver.
Disconnect the air intake hose from the throttle body.
Spray throttle body cleaner onto a cloth and wipe the throttle plate and interior surfaces.
Ensure the throttle plate moves freely and reattach the air intake hose.

5. Test and Replace Fuel Pump (if necessary)

Tools Required: Fuel pressure gauge, socket set.
Connect the fuel pressure gauge to the fuel rail.
Turn the ignition to the "ON" position (do not start) to check the pressure.
If the pressure is below specifications, replace the fuel pump.
To replace, remove the rear seat and access the fuel pump assembly; disconnect electrical connectors and fuel lines, and replace the unit.
