Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the battery to prevent electrical shorts during repairs.
Ensure the vehicle is on a level surface and the engine is cool.

2. Inspect and Replace Spark Plugs

Remove the ignition coil(s) or spark plug wires as needed.
Use a spark plug socket to remove the spark plugs.
Inspect the spark plugs for wear; replace them with OEM parts if they are worn or fouled.
Torque the new spark plugs to the manufacturer's specification (typically around 13-15 lb-ft).
Reinstall the ignition coil(s) or spark plug wires.

3. Fuel System Inspection

Connect a fuel pressure gauge to the fuel rail.
Turn the ignition key to the "on" position (do not start the engine) and check the fuel pressure reading against the manufacturer's specifications.
If pressure is low, inspect the fuel filter; replace if clogged.
If injectors are suspected to be clogged, use a fuel injector cleaner or replace them as necessary.
Reconnect the fuel line and ensure there are no leaks.

4. Air Intake System Check

Remove the air filter housing cover and inspect the air filter; replace if dirty.
Check the intake manifold for vacuum leaks using a smoke test or by visually inspecting hoses.
Clean the throttle body using throttle body cleaner if there is carbon buildup.
