Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the negative terminal of the battery to ensure safety.

2. Clean or Replace Air Filter

Remove the air filter housing cover using a socket set.
Take out the existing air filter and inspect it for dirt.
Clean the filter if reusable or replace it with a new one.
Reassemble the air filter housing.

3. Inspect and Replace Spark Plugs

Remove the ignition coil or spark plug wires (note the order for reinstallation).
Use a spark plug socket to remove the spark plugs.
Inspect the plugs for wear; replace any that are worn or fouled.
Gap the new plugs as per manufacturer specifications and install them.

4. Fuel System Check

Locate the fuel pressure test port on the fuel rail.
Connect a fuel pressure gauge and turn the ignition to the "ON" position (do not start).
Check the fuel pressure against manufacturer specifications; replace the fuel pump if pressure is low.
Disconnect the gauge and reattach the fuel line.

5. Clean Throttle Body

Remove the intake duct connected to the throttle body.
Use throttle body cleaner and a soft brush to clean the throttle plate and housing.
Reassemble the intake duct securely.
