Solution

1. Preparation

Gather necessary tools and parts for the repair.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative terminal of the battery to ensure safety during repairs.

2. Replace Air Filter

Locate the air filter housing.
Open the housing by unclipping or unscrewing as needed.
Remove the old air filter and clean any debris from the housing.
Install the new air filter, ensuring it fits snugly.
Reassemble the air filter housing.

3. Inspect and Replace Spark Plugs

Remove the ignition coils by unscrewing them from the engine.
Carefully pull out the spark plugs using a socket wrench.
Inspect the old spark plugs for wear and carbon buildup.
Install new spark plugs, tightening to the manufacturer's specified torque (typically around 13-15 ft-lbs).
Reattach the ignition coils.

4. Check for Vacuum Leaks

Start the engine and listen for hissing sounds around the intake manifold and hoses.
Use a smoke machine or carburetor cleaner to identify leaks.
Replace any damaged hoses or gaskets that are leaking.

5. Tire Maintenance

Check the tire pressure with a gauge and inflate to the recommended PSI.
Inspect the tread on each tire for uneven wear.
Rotate tires if necessary to ensure even wear.
