Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a level surface and engage the parking brake.

2. Replace Air Filter

Remove the air filter housing cover by unscrewing or unclipping it.
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 (if applicable)

3. Check and Inflate Tires

Use a tire pressure gauge to measure the pressure of each tire.
Inflate tires to the recommended PSI level specified in the owner’s manual.

Tools Required:

Tire pressure gauge
Air compressor

4. Inspect and Replace Spark Plugs

Remove the ignition coil or spark plug wires (label them for reinstallation).
Use a socket and ratchet to remove the old spark plugs.
Inspect the old plugs for wear and replace with new plugs, tightening to the manufacturer's torque specifications (usually 13-20 lb-ft).

Tools Required:

Socket set
Torque wrench

5. Clean or Replace Fuel Injectors

If injectors are clogged, use a fuel injector cleaning kit to clean them according to the kit's instructions.
If they are leaking or heavily fouled, replace with new fuel injectors.

Tools Required:

Fuel injector cleaning kit (if cleaning)
Socket set (for replacement)
