Solution

1. Preparation

Gather tools and ensure vehicle is parked on a level surface.
Disconnect the battery to prevent any electrical shorts during repairs.

2. Inspect and Clean Air Intake

Remove the air filter and inspect for dirt or obstructions.
Clean the air intake duct and the throttle body using throttle body cleaner.
Reinstall the air filter ensuring it is seated correctly.

3. Fuel System Inspection

Connect a fuel pressure gauge to the fuel rail test port.
Start the engine and check for proper fuel pressure (refer to manufacturer specifications).
If pressure is low, check the fuel pump, fuel filter, and fuel lines for blockages or damage. Replace any faulty components.

4. Throttle Body Service

Remove the throttle body from the intake manifold.
Clean the throttle plate and surrounding areas with a suitable cleaner.
Reinstall the throttle body and ensure all connections are secure.

5. Ignition System Replacement

Remove the spark plugs using a socket and ratchet.
Inspect the spark plugs for wear; replace if necessary.
Check ignition coils for proper operation; replace any faulty coils.

6. Exhaust System Check

Inspect the exhaust manifold and catalytic converter for blockages.
Replace any damaged components and ensure the exhaust system is free from leaks.
