Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Air Filter

Remove the air filter housing cover using a socket set.
Take out the old air filter and inspect it for dirt and blockages.
Install a new air filter, ensuring it fits snugly into the housing.
Reassemble the air filter housing and secure it with bolts.

3. Fuel System Inspection

Connect a fuel pressure gauge to the fuel rail’s service port.
Turn the ignition on (do not start the engine) and check the fuel pressure reading against manufacturer specifications.
- If pressure is low, proceed to replace the fuel pump.
- If pressure is adequate, proceed to inspect fuel injectors for clogs.

4. Ignition System Replacement (if necessary)

Remove the ignition coil assembly by unbolting it from the engine.
Take out the old spark plugs using a spark plug socket and inspect their condition.
Replace spark plugs with new ones and reinstall the ignition coils.
Torque the spark plugs to manufacturer specifications.

5. Exhaust System Check

Inspect the exhaust system for any visible damage or signs of blockage.
If a clogged catalytic converter is suspected, use a vacuum gauge to assess back pressure.
Replace the catalytic converter if back pressure readings exceed manufacturer limits.

6. Throttle Body Cleaning

Remove the throttle body by disconnecting the air intake and electrical connectors.
Clean the throttle body with a throttle body cleaner and a soft brush.
Reinstall the throttle body and reconnect all components.
