Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.
Allow the engine to cool down before starting the work.

2. Address Air Intake Issues

Remove the air intake hose and inspect for blockages or damage.
Clean or replace the air filter if clogged.
Reassemble the air intake system and secure all clamps.

3. Fuel System Repair

Use a fuel pressure gauge to check the fuel pump's output.
If pressure is low, replace the fuel pump and filter as needed.
Ensure fuel lines are not kinked or damaged.

4. Ignition System Repair

Remove the spark plugs for inspection; replace if worn or fouled.
Test ignition coils using a multimeter; replace if out of specification.
Reinstall all components ensuring proper torque specifications are met.

5. Throttle Body Cleaning

Remove the throttle body from the intake manifold.
Clean the throttle body using throttle body cleaner and a soft brush.
Reinstall the throttle body, ensuring all gaskets are intact and properly seated.

6. Exhaust System Inspection

Inspect the exhaust system for any visible damage or rust.
Check the catalytic converter for signs of clogging; replace if necessary.
Reinstall any removed components and ensure secure connections.
