Solution

1. Preparation

Park the vehicle on a flat surface and engage the parking brake.
Disconnect the negative terminal of the battery to ensure safety while working on electrical components.
Gather tools and parts needed for repairs.

2. Replace Air Filter

Remove the air filter housing cover by loosening the clamps or screws.
Take out the old air filter and inspect the housing for debris.
Install a new air filter, ensuring it fits snugly, and reattach the housing cover.
Tools Required: Screwdriver, socket set.

3. Clean Throttle Body

Remove the throttle body from the intake manifold by disconnecting the throttle position sensor and air intake duct.
Use throttle body cleaner and a soft cloth to clean the inside of the throttle body.
Reinstall the throttle body and reconnect all sensors and hoses.
Tools Required: Socket set, throttle body cleaner.

4. Replace Spark Plugs

Remove the ignition coil connectors and unscrew the coils.
Use a spark plug socket to carefully unscrew and remove the old spark plugs.
Install new spark plugs, ensuring they are gapped correctly according to manufacturer specifications.
Reattach the ignition coils and connectors.
Tools Required: Spark plug socket, torque wrench.

5. Inspect and Test Fuel System

Remove the fuel pump relay from the fuse box and jump the terminals to activate the pump.
Use a fuel pressure gauge to measure the fuel pressure at the fuel rail.
If pressure is low, consider replacing the fuel pump or checking for clogged fuel filters.
Tools Required: Fuel pressure gauge.
