Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface with the engine off.
Disconnect the battery to ensure safety when working on electrical components.

2. Replace Air Filter

Remove the air filter housing cover using a socket set.
Take out the old air filter and inspect the housing for debris.
Install the new air filter, ensuring it fits snugly.
Reattach the housing cover and secure it properly.

3. Address Fuel System Issues

If leaks are detected, locate the source and replace the faulty fuel lines or connections as needed.
Use a fuel pressure gauge to check the fuel pump pressure against manufacturer specifications.
Replace the fuel filter if it is clogged or has not been changed per maintenance schedule.

4. Replace Spark Plugs

Remove the ignition coil or distributor cap to access the spark plugs.
Use a socket set to unscrew the old spark plugs.
Check the gap on the new spark plugs and adjust if necessary.
Install the new spark plugs and reconnect the ignition components.

5. Check and Inflate Tires

Use a tire pressure gauge to check the pressure of all four tires.
Inflate tires to the recommended PSI found in the driver's door jamb.
Inspect the tread for uneven wear, which may indicate alignment issues.
